- the innovation relates to an insole for a shoe that extends at least over the forefoot, preferably the entire foot, the sole, with a spring steel plate, the bending stiff in the transverse direction of the sole, especially in Abroll Scheme the sole, however, in the longitudinal direction of the sole is bendable vertically and after Resetting load elastically, wherein the spring steel plate has over the entire sole region a preferably perpendicular, running to the sole longitudinal direction transverse profile, and with a plastic layer in which the spring steel plate is arranged.
- Such insoles are from the EP 373 336 A1 . US5720118 , and EP 1 189 527 A1 known. They give the wearer of a shoe a comfortable fit, because the insoles give due to their stability of the sole of a shoe a higher stability than conventional soles. Furthermore, the high spring force of the spring steel of the insole gives an improved ride, since the spring and remindstelleingenschaften the metal material have a favorable effect on the Gehbefinden the wearer.
- a disadvantage of a spring steel material is its limited shock absorption property, ie the energy applied to the spring steel material by a falling part of the weight is absorbed only to a limited extent by such a metal plate, the remaining energy being released via the spring back of the metal plate to the rebounding weight part. Transferred to such in-shoe insole, for the wearer, means that the shoe rebounds when running, with the rebound energy delivered being introduced into and absorbed by the foot of the wearer.
- shoe insoles In order to improve the shock absorption ability, gel shoe inserts have been proposed as a shoe insole. Such shoe insoles are for example in "Plastics” Issue 8 (2005), page 56 - 58th shown. Other shoe insoles made of a gel are in the DE 20 2005 005011U1 . US 2012 / 0023776A1 or WO 2007/092091 A2 described.
- Gel materials have the property that they are not only compressed as plastic foams when pressure is applied, but also dodge sideways and thus deform elastically in all three spatial directions and reset after relief again on the nature of the memory effect. Parts of the gel molecules are quasi-liquid and flowable within the remaining gel matrix. They are partly chemically bound, partly physically held on the matrix in a highly complex equilibrium process and are deformed under pressure loading under deformation of the matrix. This deformation is essentially reversible and thus leads to absorption and absorption of the transmitted kinetic energy of the impacting body when loaded.
- the novelty is therefore based on the object to provide an insole of the type mentioned above, which has an improved shock absorption behavior.
- polyurethane components can be used, as in the EP 57 838 A1 and EP 511 570 A1 are described.

- the isocyanates can be present either in pure form or as modified isocyanate.
- fillers and / or additives known from polyurethane chemistry may be added in a total amount of up to 50% by weight, based on the total weight of the gel mass.
- the weight ratio of the polyisocyanate component to the polyol component is 1: 6.5 to 1: 8. This leads with increasing weight ratio to an ever softer elastic solid gel. Thus, with an increase in the weight ratio, the Shore hardness 00 (measured to ASTM D 2240) falls from about 80 to about 35 at room temperature.
- inventive Shore-hardening 00 are in a range of 45-70, in particular 52-64 at room temperature and are determined according to ASTM D 2240.
- the isocyanate component and the polyol component are mixed together in the one-shot process, wherein the resulting mixture has to be processed and poured into the mold within the pot life (usually 5 to 15 minutes).
- the choice of the mixing ratio of the polyisocyanate component and polyol component depends on the desired hardness of the gel, wherein the specific structure of the materials used and optionally an added catalyst, the effect of which has an increased hardness value of the gel result is observed. Ultimately, the determined One skilled in the art empirically the mixing ratio and the mixing parameters to get to the desired hardness value of the gel.

- the inventive insole has a sole made essentially of spring steel and gel, which is usually used as a separate support sole in the shoe. On the other hand, however, this insole can be used as an insole with appropriate design of the edges.
- the spring steel sole used as inlay within the gel bed is flexible in the longitudinal direction and stiff in the transverse direction and usually cushions the foot in its ball area.
- a transverse or wave profile supports the rolling of the foot.
- the support sole grasps only the front ball area, while a second embodiment covers the entire foot with front area and heel area. It is anatomically adjusted according to the shape of the shoe or the shape of the foot, so available in sizes corresponding to the different shoe sizes.

- the rigid plate-shaped material is completely surrounded by a gel edge, which thus surrounds the side edges of the plate material substantially annular.
- a complete sheathing of the plate-shaped material is achieved, thus achieving a further stabilization of this composite arrangement.
- the cured gel Due to its adhesiveness during the polymerization phase, the cured gel has high adhesion to the plate-shaped material and can only be detached from the spring steel plate by destroying the entire arrangement. If the plate-shaped material is deformed in the longitudinal direction while walking, the gel layer is compressed on the upper side of the plate and stretched on the underside, so that the recoverability of the plate-shaped material is improved from the deformed state to the initial state.

Description
Die Neuerung betrifft eine Einlegesohle für einen Schuh, die sich zumindest über den Vorderfußbereich, vorzugsweise den gesamten Fußbereich, der Sohle erstreckt, mit einer Federstahlplatte, die in Sohlenquerrichtung, insbesondere im Abrollbereich der Sohle biegesteif, dagegen in der Sohlenlängsrichtung vertikal biegeweich ist und sich nach Belastung elastisch rückstellt, wobei die Federstahlplatte im Wesentlichen über den gesamten Sohlenbereich ein vorzugsweise senkrecht, zur Sohlenlängsrichtung laufendes Querprofil aufweist, und mit einer Kunststoffschicht, in der die Federstahlplatte angeordnet ist.The innovation relates to an insole for a shoe that extends at least over the forefoot, preferably the entire foot, the sole, with a spring steel plate, the bending stiff in the transverse direction of the sole, especially in Abrollbereich the sole, however, in the longitudinal direction of the sole is bendable vertically and after Resetting load elastically, wherein the spring steel plate has over the entire sole region a preferably perpendicular, running to the sole longitudinal direction transverse profile, and with a plastic layer in which the spring steel plate is arranged.
Derartige Einlegesohlen sind aus der
Nachteilig an einem Federstahlmaterial ist jedoch seine beschränkte Schockabsorptionseigenschaft, d.h. die durch ein fallendes Gewichtsteil auf das Federstahlmaterial aufgebrachte Energie wird nur beschränkt von einer derartigen Metallplatte absorbiert, wobei die restliche Energie über die Rückfederung der Metallplatte an das zurückprallende Gewichtsteil abgegeben wird.
Übertragen auf eine derartige in einem Schuh befindliche Einlegesohle bedeutet dies für den Schuhträger, dass der Schuh beim Laufen nachfedert, wobei die abgegebene Rückprallenergie in den Fuß des Trägers eingeleitet wird und dort absorbiert werden muss. Führt man in Anlehnung an ASTM F 1976 einen Schockabsorptionstest durch, so stellt man an einer Federstahlsohle gemäß
A disadvantage of a spring steel material, however, is its limited shock absorption property, ie the energy applied to the spring steel material by a falling part of the weight is absorbed only to a limited extent by such a metal plate, the remaining energy being released via the spring back of the metal plate to the rebounding weight part.
Transferred to such in-shoe insole, for the wearer, means that the shoe rebounds when running, with the rebound energy delivered being introduced into and absorbed by the foot of the wearer. If, on the basis of ASTM F 1976, a shock absorption test is carried out, then the adjustment is made on a spring steel sole according to
Wünschenswert ist daher eine verbesserte Einlegesohle mit erhöhten Schockabsorptionseigenschaften, gegenüber in der
Zu Verbesserung der Schockabsorptionsfähigkeit wurden bereits Schuheinlagen aus Gel als Schuheinlegesohle vorgeschlagen.
Gel-Materialien haben die Eigenschaft, dass sie anders als Kunststoffschäume bei Ausübung von Druck nicht nur zusammengedrückt werden, sondern vielmehr auch seitlich ausweichen und somit sich in allen drei Raumrichtungen elastisch verformen und sich nach Entlastung wieder nach Art des Memory-Effekts zurückstellen. Teile der Gelmoleküle sind nämlich quasi-flüssig und innerhalb der übrigen Gelmatrix fließfähig. Sie sind teils chemisch gebunden, teils physikalisch an der Matrix gehalten in einem hochkomplexen Gleichgewichtsprozess und werden bei Druckbelastung unter Deformierung der Matrix verformt. Diese Verformung läuft im Wesentlichen reversibel ab und führt bei Belastung somit zur Aufnahme und Absorption der übertragenen kinetischen Energie des aufprallenden Körpers.Gel materials have the property that they are not only compressed as plastic foams when pressure is applied, but also dodge sideways and thus deform elastically in all three spatial directions and reset after relief again on the nature of the memory effect. Parts of the gel molecules are quasi-liquid and flowable within the remaining gel matrix. They are partly chemically bound, partly physically held on the matrix in a highly complex equilibrium process and are deformed under pressure loading under deformation of the matrix. This deformation is essentially reversible and thus leads to absorption and absorption of the transmitted kinetic energy of the impacting body when loaded.
Ein analoger Test, wie vorstehend beschrieben, hat nun ergeben, dass die Schockabsorptionsqualität einer Einlegesohle aus Gelmaterial allein kein wesentlich besseres Absorptionsverhalten hat als die Metallsohle allein. So absorbiert eine Gelsohle im Ballen-/Fersenbereich ca. 65% bzw. 63% der eingetragenen Energie gemäß dem vorstehend genannten Test.An analogous test, as described above, has now shown that the shock absorption quality of an insole made of gel material alone does not have a significantly better absorption behavior than the metal sole alone. Thus, a gel sole in the ball / heel area absorbs about 65% or 63% of the energy input according to the test mentioned above.
Der Neuerung liegt daher die Aufgabe zugrunde, eine Einlegesohle der eingangs erwähnten Art zur Verfügung zu stellen, die ein verbessertes Schockabsorptionsverhalten aufweist.The novelty is therefore based on the object to provide an insole of the type mentioned above, which has an improved shock absorption behavior.

Wie bereits vorstehend erwähnt, beträgt in einer bevorzugten Ausführungsform das Gewichtsverhältnis der Polyisocyanat-Komponente zur Polyol-Komponente 1:6,5 bis 1:8. Dies führt mit steigendem Gewichtsverhältnis zu einem immer weicheren elastischen festen Gel. Es fällt also mit Zunahme des Gewichtsverhältnisses die Shore-Härte 00 (gemessen nach ASTM D 2240) von ca. 80 auf ca. 35 bei Raumtemperatur.As already mentioned above, in a preferred embodiment, the weight ratio of the polyisocyanate component to the polyol component is 1: 6.5 to 1: 8. This leads with increasing weight ratio to an ever softer elastic solid gel. Thus, with an increase in the weight ratio, the Shore hardness 00 (measured to ASTM D 2240) falls from about 80 to about 35 at room temperature.

Ultimately, the determined One skilled in the art empirically the mixing ratio and the mixing parameters to get to the desired hardness value of the gel.
Die integrierte Sohle aus Gel und Metallplatte wird in einem üblichen Gussverfahren in einer üblichen Form, wie sie beispielsweise bei der Gelherstellung verwendet wird, hergestellt. Das in der Neuerungsgemäßen Sohle gebildete Verbundmaterial weist verbesserte Feder- und Dämpfungseigenschaften gegenüber denjenigen der Einzelmaterialien auf, so dass sich eine Verbesserung der Schockabsorsoptionseigenschaften der Neuerungsgemäßen Sohle ergibt.The integrated sole of gel and metal plate is made in a conventional casting process in a conventional form, such as used in gel manufacture. The composite formed in the inventive sole has improved spring and cushioning properties over those of the individual materials, resulting in an improvement in the shock absorbency properties of the inventive sole.
Vorteilerhafterweise weist die aus Gel- und Metallplatte bestehende Sohle zumindest einseitig eine äußere Abdeckschicht auf, die für das Polyurethan-Gel undurchlässig ist.Advantageously, the sole made of gel and metal plate at least on one side an outer cover layer, which is impermeable to the polyurethane gel.
Eine solche Abdeckschicht kann aus einer Folie, Leder, Kunstleder oder einem textilem Material, beispielsweise einem für das PU-Gel undurchlässigen Mikrofasermaterial bestehen. Vorzugweise wird als Abdeckmaterial Leder oder ein dem Leder nachgebildetes Kunststoffmaterial eingesetzt. Die Abdeckschicht verfolgt dabei nicht nur den Zwecke, für den Komfort des Schuhbenutzers, sondern vielmehr auch für die Stabilisierung der Gel-Oberfläche bei dem Einwirken der Fußunterseite im Benutzungszustand zu dienen.Such a cover layer may consist of a film, leather, synthetic leather or a textile material, for example a microfiber material impermeable to the PU gel. Preferably, the cover material used is leather or a plastic material simulated to the leather. The cover layer not only pursues the purpose of serving for the comfort of the shoe user, but also for the stabilization of the gel surface in the action of the underside of the foot in the state of use.

Die Neuerungsgemäße Einlegesohle weist eine im Wesentlichen aus Federstahl und Gel gefertigte Sohle auf, die üblicherweise als separate Stützsohle im Schuh eingesetzt wird. Andererseits kann aber auch diese Einlegesohle als Brandsohle bei entsprechender Ausbildung der Ränder verwendet werden.The inventive insole has a sole made essentially of spring steel and gel, which is usually used as a separate support sole in the shoe. On the other hand, however, this insole can be used as an insole with appropriate design of the edges.
Die als Inlay innerhalb des Gelbettes verwendete Federstahlsohle ist in Längsrichtung flexibel und Querrichtung steif und polstert üblicherweise den Fuß in seinem Ballenbereich ab. Zusätzlich unterstützt ein Quer- bzw. Wellenprofil das Abrollen des Fußes.The spring steel sole used as inlay within the gel bed is flexible in the longitudinal direction and stiff in the transverse direction and usually cushions the foot in its ball area. In addition, a transverse or wave profile supports the rolling of the foot.
Gemäß seiner ersten Ausführungsform erfasst die Stützsohle nur den vorderen Ballenbereich, während eine zweite Ausführungsform den gesamten Fuß mit Vorderbereich und Fersenbereich abdeckt. Dabei ist sie entsprechend der Schuhform bzw. der Form des Fußes anatomisch angepasst, also in Größen entsprechend den verschiedenen Schuhgrößen erhältlich. Die Querprofilierung kann sich sowohl über den Vorderfußbereich als auch über den Fersenbereich erstrecken. Dabei verläuft das Querprofil vorteilhafterweise nach Art einer Sinus-Welle, wobei die Größe der Gesamthöhe bei 0,5-2 mm, vorteilhafterweise bei ca. 1,3-1,6 mm liegt. Die Wellenlänge der Welle liegt vorteilhafterweise bei 3-5 mm, bevorzugt bei 7-12, insbesondere bei ca. 10 mm.According to its first embodiment, the support sole grasps only the front ball area, while a second embodiment covers the entire foot with front area and heel area. It is anatomically adjusted according to the shape of the shoe or the shape of the foot, so available in sizes corresponding to the different shoe sizes. The transverse profiling may extend over both the forefoot and heel regions. In this case, the transverse profile advantageously proceeds in the manner of a sine wave, the size of the total height being 0.5-2 mm, advantageously about 1.3-1.6 mm. The wavelength of the wave is advantageously 3-5 mm, preferably 7-12, in particular about 10 mm.
Die Querprofilierung selbst verläuft vorzugsweise zumindest im Vorderfußbereich in einem bestimmten ersten Winkel zur Längsrichtung der Sohle, insbesondere zwischen 70° - 90°, vorteilhafterweise zwischen 75° und 80°. Auch im Fersenbereich kann sich die Querprofilierung mit diesen Winkeln erstrecken.The transverse profiling itself preferably runs at least in the forefoot region at a specific first angle to the longitudinal direction of the sole, in particular between 70 ° -90 °, advantageously between 75 ° and 80 °. Even in the heel area, the transverse profiling can extend at these angles.
Um eine natürliche Abrollbewegung zu unterstützen, können die Wellen im Rück- oder Hinterfussbereich (Fersenbereich) auch in einem vom ersten Winkel abweichenden zweiten Winkel verlaufen, welcher vorzugsweise zwischen 90° und 110° liegt.In order to support a natural rolling movement, the waves in the rear or rear foot region (heel region) can also run in a second angle deviating from the first angle, which is preferably between 90 ° and 110 °.
Gemäß einer weiteren bevorzugten Ausführungsform beträgt der Winkel in beiden Bereichen (Vorderfuss- und Hinterfussbereich) etwa 90°.According to a further preferred embodiment, the angle in both areas (forefoot and hindfoot area) is approximately 90 °.
Das aus Federstahl bestehende harte elastische Plattenmaterial weist eine gleichförmige Dicke, von 0,1-0,6 mm, vorzugweise ca. 0,2 mm - 0,4 mm, insbesondere 0,25 mm - 0,35 mm auf.The spring-elastic hard plate material has a uniform thickness of 0.1-0.6 mm, preferably about 0.2 mm-0.4 mm, especially 0.25 mm-0.35 mm.
Gemäß einer weiteren Ausführungsform kann die Quer- und/oder Längsprofilierung auch eine andere Form im Querschnitt aufweisen, beispielsweise eine Rillen-, Riefen-, Rippen-, Rinnen-, Riffel- oder Sickenform.According to a further embodiment, the transverse and / or longitudinal profiling can also have a different shape in cross section, for example a groove, groove, rib, gutter, corrugation or bead shape.
Bei dem Neuerungsgemäßen Verbundplattenmaterial sind die jeweiligen Wellentäler der Querprofilierung vollständig mit dem PU-Gel ausgefüllt, wobei die Dicke der Gelschicht zusätzlich größer ist als die Gesamthöhe des Querprofils. Vorteilhafterweise ist die Dicke der Gelschicht einheitlich, so dass die Verbundsohle eine ebene und glatte Oberfläche sowohl auf ihrer Oberseite als auch ihrer Unterseite mit völlig glatter Struktur aufweist.In the novel composite panel material, the respective troughs of the transverse profiling are completely filled with the PU gel, wherein the thickness of the gel layer is additionally greater than the total height of the transverse profile. Advantageously, the thickness of the gel layer is uniform, so that the composite sole has a flat and smooth surface both on its upper side and its underside with a completely smooth structure.
Die Gesamthöhe der Querprofilierung der Federstahlplatte selbst liegt zwischen 0,5 und 2,5 mm, vorzugsweise bei 1-2 mm, insbesondere bei ca. 1,5 mm.The overall height of the transverse profiling of the spring steel plate itself is between 0.5 and 2.5 mm, preferably at 1-2 mm, in particular at about 1.5 mm.
Desweiteren beträgt die Dicke der Gelschicht das 1,5-4-fache, insbesondere das 1,8-3,5 fache, besonders bevorzugt ca. das 2,5-3-fache bezogen auf die Gesamthöhe der Querprofilierung,Furthermore, the thickness of the gel layer is 1.5-4 times, in particular 1.8-3.5 times, particularly preferably approximately 2.5-3 times, based on the total height of the transverse profiling,
Zum Begriff "Gesamthöhe" ist zu bemerken, dass dieser die Höhe eines sich aus der Ebene erstreckenden Profils beliebiger Art kennzeichnet.The term "total height" is to be understood as indicating the height of a profile of any kind extending out of the plane.
Bei einer besonders bevorzugten Ausführungsform beträgt die Gesamthöhe des Profils einschließlich der Plattenstärke ca. 1,5mm und die Gesamtstärke des Gels ca. 4mm, wobei die Dicke der Federstahlplatte bei ca. 0,3 mm liegt.In a particularly preferred embodiment, the overall height of the profile including the plate thickness is about 1.5mm and the total thickness of the gel is about 4mm, with the thickness of the spring steel plate being about 0.3mm.
Während gemäß einer ersten Ausführungsform die Federstahlplatte mit ihren jeweiligen Wellenbergen mit gleichen Abständen zu den oberen und unteren Außenflächen der PU-Schicht in der Gelschicht angeordnet ist, also die Gelschicht um den gleichen Betrag d1 und d2 jeweils auf der Unter- und Oberseite des Profils übersteht, kann gemäß einer zweiten Ausführungsform auch die Größe der überstehenden Schichten d1 und d2 unterschiedlich sein. Gemessen werden jeweils d1 und d2 der Gelschichten sowie die Gesamthöhe H des Profils. Dabei kann das Verhältnis von d1 : H bzw d2 : H einen Betrag von 0,5:1 bis 1,5:1, vorzugsweise 0,8:1 bis 1,2:1 annehmen.While according to a first embodiment, the spring steel plate with their respective crests with equal distances to the upper and lower outer surfaces of the PU layer is arranged in the gel layer, that is, the gel layer by the same amount d1 and d2 respectively on the bottom and top of the profile, according to a second embodiment, the size of the protruding layers d1 and d2 may be different. In each case d1 and d2 of the gel layers as well as the total height H of the profile are measured. The ratio of d1: H or d2: H can assume an amount of 0.5: 1 to 1.5: 1, preferably 0.8: 1 to 1.2: 1.
Gemäß einer weiteren bevorzugten Ausführungsform ist das starre plattenförmige Material vollständig von einem Gelrand umfasst, der somit die Seitenränder des Plattenmaterials im Wesentlichen ringförmig umgibt. Hierdurch wird eine vollständige Ummantelung des plattenförmigen Materials erreicht und damit eine weitere Stabilisierung dieser Verbundanordnung erreicht. Das ausgehärtete Gel besitzt aufgrund seiner Klebefähigkeit während der Polymerisationsphase eine hohe Haftung an dem plattenförmigen Material erhält und kann nur unter Zerstörung der gesamten Anordnung von der Federstahlplatte abgelöst werden. Wird das plattenförmige Material in Längsrichtung beim Gehen verformt, so wird die Gelschicht auf der Oberseite der Platte gestaucht und auf der Unterseite gestreckt, so dass die Rückstellfähigkeit des plattenförmigen Materials vom verformten Zustand in den Ausgangszustand verbessert wird. Dabei löst sich die Gelschicht weder beim Stauchen noch beim Strecken von der Metalloberfläche und bleibt dort haften.According to a further preferred embodiment, the rigid plate-shaped material is completely surrounded by a gel edge, which thus surrounds the side edges of the plate material substantially annular. As a result, a complete sheathing of the plate-shaped material is achieved, thus achieving a further stabilization of this composite arrangement. Due to its adhesiveness during the polymerization phase, the cured gel has high adhesion to the plate-shaped material and can only be detached from the spring steel plate by destroying the entire arrangement. If the plate-shaped material is deformed in the longitudinal direction while walking, the gel layer is compressed on the upper side of the plate and stretched on the underside, so that the recoverability of the plate-shaped material is improved from the deformed state to the initial state. In the process, the gel layer does not detach from the metal surface during compression nor during stretching and remains adherent there.
Es lassen sich mit der Neuerungsgemäßen Einlegesohle alle möglichen Arten von Schuhen verwenden, wobei hier nicht nur Halbschuhe, sondern auch Stiefel, hohe Schuhe und dergleichen verstanden werden. Die Sohle selbst unterstützt und schützt das Fußgewölbe und bietet Schutz im Ballenbereich, wobei der Fuß durch die verbesserte Schockabsorptionsfähigkeit des Belastungsdrucks weniger ermüdet.It can be used with the innovation insole all sorts of shoes, here not only low shoes, but also boots, high shoes and the like are understood. The sole itself supports and protects the arch of the foot and offers protection in the ball area, whereby the foot is less fatigued due to the improved shock absorption capacity of the load pressure.
Des Weiteren lässt sich die Neuerungsgemäße Sohle für normale Schuhe, beispielsweise Straßen- und Laufschuhe, insbesondere Sportschuhe verwenden. Sie hat eine leistungssteigernde und gesundheitsschützende Wirkung. Desgleichen wird durch die starre Plattenstruktur der Verletzungsgefahr bei Füßen, insbesondere im Arbeitsbereich vorgebeugt.Furthermore, the innovative sole for normal shoes, such as road and running shoes, especially sports shoes can be used. It has a performance-enhancing and health-protective effect. Likewise, the rigid plate structure prevents the risk of injury to feet, especially in the working area.

Bei der Messung von physikalischen Parametern kommen folgende Test-Methoden zum Einsatz.When measuring physical parameters, the following test methods are used.
Bei der Schockabsorption (Impact Test) wurde in Anlehnung an ASTM F 1976 Prüfungen im Fersen- und Ballenbereich durchgeführt. Hierbei wird der Aufprall des menschlichen Fußes auf den Boden mit Hilfe einer freifallenden Masse von 7,5 kg simuliert. Der Aufprall der freifallenden Masse auf den Prüfling erfolgt bei einer genau festgelegten Geschwindigkeit von 0,5 m/s. Während der Deformation des Materials nimmt die Geschwindigkeit der Fallmasse ab. Dabei ist die Änderung der Geschwindigkeit pro Zeiteinheit ein Maß für die Bremswirkung des Materials.The shock absorption test was carried out in accordance with ASTM F 1976 in the heel and ball area. Here, the impact of the human foot on the ground is simulated using a free-falling mass of 7.5 kg. The impact of the free-falling mass on the test specimen takes place at a precisely defined speed of 0.5 m / s. During the deformation of the material, the velocity of the falling mass decreases. The change in speed per unit time is a measure of the braking effect of the material.
Bei der Durchführung des Versuchs wird die Maximalbeschleunigung der Masse beim Kontakt mit dem Prüfkörper gemessen und gleichzeitig die Eindringtiefe und die Rückprallhöhe ermittelt. Außerdem werden die aufgenommene Energie, die abgegebene und absorbierte Energie gemessen. Anschließend wird u.a. das prozentuale Absorptionsverhältnis und die Federkonstante berechnet.When carrying out the experiment, the maximum acceleration of the mass is measured on contact with the test specimen and at the same time the penetration depth and the rebound height are determined. In addition, the absorbed energy, the emitted and absorbed energy are measured. Subsequently, among other things, the percentage absorption ratio and the spring constant is calculated.
