Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines Druckbehälters, insbesondere für ein Kraftfahrzeug, insbesondere als Drucktank für Wasserstoff, nach dem Oberbegriff des ersten Anspruchs.The invention relates to a method for producing a pressure vessel, in particular for a motor vehicle, in particular as a pressure tank for hydrogen, according to the preamble of the first claim.
Es ist bereits bekannt, Wasserstoff als Kraftstoff für Kraftfahrzeuge zu verwenden und diesen dazu in einem Drucktank unter Überdruck zu speichern. Derartige Drucktanks können aus Stahl bestehen. Für einen höheren Fülldruck kann zum Beispiel ein solcher, im wesentlichen zylindrischer Stahltank durch einen Faserverbundwerkstoff mit beispielsweise Glas- und/oder Kohlenstofffasern umwickelt werden.It is already known to use hydrogen as a fuel for motor vehicles and to store this in a pressure tank under pressure. Such pressure tanks can be made of steel. For example, for a higher inflation pressure, such a substantially cylindrical steel tank may be wrapped by a fiber composite with, for example, glass and / or carbon fibers.
Ein solcher Druckbehälter ist aus der
Wird also der Druckbehälter durch seinen Inhalt bedruckt, wird zunächst eine Druckvorspannung im Liner aus der Autofrettage ausgeglichen und erst bei weiter ansteigendem Innendruck die Behälterwandung nach außen hin auf Zug beansprucht.Thus, if the pressure vessel is printed by its contents, first a pressure bias in the liner from the autofrettage is compensated and only when the internal pressure continues to increase does the container wall become stressed towards the outside.
Bei der Herstellung eines solchen Druckbehälters ist es üblich, dass für eine Behälterserie werkstoffabhängig ein fester Autofrettagedruck festgelegt und für alle Behälter dieser Serie angewandt wird. In Werkstoffnormen wird für die Streckgrenze allerdings ein vom Werkstoff erfüllbarer Mindestwert angegeben, der für eine Auslegung gegen Versagen benötigt wird. Für eine optimale Autofrettage ist jedoch der genaue Wert der Streckgrenze für den vorliegenden Werkstoff von Bedeutung, da eine bestimmte plastische Dehnung angestrebt wird. Der optimale Grad der Qualitätsverbesserung durch die Autofrettage wird also durch eine solche Vorbestimmung des maximalen Autofrettagedrucks erzielt, mit dem die höchstmögliche Vorspannung im Liner durch Plastifizierung erzeugt werden kann. Das Resultat hängt dabei in erster Linie von der tatsächlichen Streckgrenze des Linerwerkstoffes ab, da durch eine diese annähernd überschreitende Belastung bei der Autofrettage der Wert der späteren Vorspannung im Liner bestimmt wird.In the production of such a pressure vessel, it is common for a container series material-dependent fixed a fixed autofrettage and applied to all containers of this series. In material standards, however, the yield strength is given a minimum value that can be met by the material and is required for design against failure. For optimal autofrettage, however, the exact value of the yield strength is of importance for the present material, since a certain plastic strain is desired. The optimal degree of quality improvement by the autofrettage is thus achieved by such a predetermination of the maximum autofrettage pressure, with which the highest possible bias in the liner can be generated by plasticization. The result depends primarily on the actual yield strength of the liner material, since the value of the later bias in the liner is determined by an approximately exceeding stress in autofrettage.
Der Erfindung liegt deshalb die Aufgabe zugrunde, ein Verfahren zur Herstellung eines Druckbehälters der eingangs genannten Art so weiter zu entwickeln, dass dieses obige Nachteile vermeidet und mit dem gezielt die Vorspannungszustände eines Druckbehälters optimiert werden können.The invention is therefore based on the object to develop a method for producing a pressure vessel of the type mentioned so that this avoids the above disadvantages and can be optimized with the targeted the bias conditions of a pressure vessel.
Die Aufgabe wird durch die Merkmale und Verfahrensschritte des ersten Anspruchs gelöst. Bevorzugte Ausgestaltungen der Erfindung beschreiben die abhängigen Ansprüche.The object is achieved by the features and method steps of the first claim. Preferred embodiments of the invention describe the dependent claims.
Bei einem Verfahren nach der Erfindung wird ein Druckbehälter aus einem metallischen Liner hergestellt, indem dieser außen mit Faserverbundwerkstoff verstärkt und nach dem Aushärten des Matrixwerkstoffes einer Autofrettage-Behandlung durch Innendruckerhöhung unterworfen wird. Die Erfindung zeichnet sich dadurch aus, dass vor der Autofrettage-Behandlung eine maximale plastische Dehnung des Druckbehälters in wenigstens einer Richtung bestimmt wird und während der Autofrettage-Behandlung die plastische Dehnung des Druckbehälters gemessen wird und der Autofrettagedruck bei Erreichen der maximalen plastischen Dehnung nicht weiter erhöht wird.In a method according to the invention, a pressure vessel made of a metallic liner is made by externally reinforced with fiber composite material and is subjected to curing of the matrix material of an autofrettage treatment by increasing the internal pressure. The invention is characterized in that before the autofrettage treatment, a maximum plastic strain of the pressure vessel is determined in at least one direction and during the autofrettage treatment, the plastic strain of the pressure vessel is measured and the autofrettage pressure is not further increased upon reaching the maximum plastic strain becomes.
Dadurch wird vorteilhafterweise auch bei Schwankungen bezüglich der Streckgrenze in verschiedenen Materialchargen ein gleiches Ergebnis hinsichtlich der Behältervorspannung erzielt, wodurch eine Streuung in der Performance und Lebensdauer der Behälter reduziert wird.As a result, an equal result in terms of container bias is advantageously achieved even with fluctuations in the yield strength in different batches of material, whereby a dispersion in the performance and life of the container is reduced.
Das Messen der momentan erreichten Dehnung des Druckbehälters kann beispielsweise über Dehnmessstreifen oder über Umfangsmessung, insbesondere mittels eines Umfangsbandes, erfolgen. Dabei ist es vorteilhaft, wenn die festgelegte maximale Dehnung eine Dehnung in Umfangsrichtung des Druckbehälters ist und diese bzw. deren Erreichen durch iteratives Erhöhen des Autofrettagedrucks mit zwischenzeitlichem Messen der momentan erreichten Dehnung des Druckbehälters erfolgt, wozu ein Steuergerät schrittweise jeweils aus der Differenz der maximalen Dehnung des Druckbehälters abzüglich der momentanen Dehnung des Druckbehälters den nächsten Wert der Erhöhung des Autofrettagedrucks festlegt bis die maximale Dehnung des Druckbehälters erreicht ist. Dabei kann alternativ die festgelegte maximale Dehnung des Druckbehälters eine plastische Dehnung sein und die momentane plastische Dehnung an dem vom Autofrettagedruck entlasteten Druckbehälter bestimmt werden oder die festgelegte maximale Dehnung des Druckbehälters eine Gesamtdehnung aus elastischer und plastischer Dehnung sein und die momentane elastische und plastische Dehnung an dem unter Autofrettagedruck stehenden Druckbehälter bestimmt werden. Bei dem Druckbehälter handelt es sich vorteilhafterweise um einen Typ 3 Druckbehälter dessen maximale Dehnung anhand tatsächlicher Werkstoff-Festigkeitswerte, insbesondere der Streckgrenze, insbesondere im Steuergerät, festgelegt werden kann. Dabei ist es dann vorteilhaft, wenn im Steuergerät die Mess- und Kennwerte, insbesondere eine Serie iterativ erhöhter Autofrettagedrücke, für einen Herstellungsvorgang eines Druckbehälters so speicher- und abrufbar sind, dass aus einer Materialcharge mit gleichen Festigkeitswerten eine Serie gleicher Druckbehälter hergestellt werden kann, unter der Verwendung der Mess- und Kennwerte aus der Herstellung des ersten Druckbehälters davon. The measuring of the momentarily reached expansion of the pressure vessel can take place, for example, via strain gauges or via circumferential measurement, in particular by means of a peripheral band. It is advantageous if the specified maximum elongation is an elongation in the circumferential direction of the pressure vessel and this or their achievement is achieved by iteratively increasing the Autofrettagedrucks with interim measurement of the momentarily achieved expansion of the pressure vessel, including a control unit stepwise from the difference of the maximum elongation the pressure vessel minus the instantaneous expansion of the pressure vessel determines the next value of the increase of the autofrettage pressure until the maximum expansion of the pressure vessel is reached. Alternatively, the predetermined maximum elongation of the pressure vessel may be a plastic strain and the instantaneous plastic strain at the pressure vessel relieved of the pressure vessel may be determined or the specified maximum strain of the pressure vessel may be a total strain of elastic and plastic strain and the instantaneous elastic and plastic strain on the pressure vessel be determined under Autofrettagedruck pressure vessel. The pressure vessel is advantageously a type 3 pressure vessel whose maximum expansion can be determined on the basis of actual material strength values, in particular the yield strength, in particular in the control unit. In this case, it is advantageous if the measurement and characteristic values, in particular a series of iteratively increased autofrettage pressures, are storable and retrievable in the control unit for a production process of a pressure vessel such that a series of equal pressure vessels can be produced from a material charge having the same strength values the use of the measurement and characteristic values from the production of the first pressure vessel thereof.
Bevorzugt werden nach diesem Verfahren hergestellte Druckbehälter in Kraftfahrzeugen als Drucktanks, insbesondere für Wasserstoff, verwendet. Grundsätzlich können derartig ausgebildete Druckbehälter aber auch auf allen anderen Gebieten der Technik eingesetzt werden, beispielsweise als stationärer Vorratsbehälter zur Energiegewinnung in einer Brennstoffzelle. Auch können bei geeigneter Materialwahl andere Gase eingefüllt werden.Preference is given to pressure vessels produced by this method used in motor vehicles as pressure tanks, in particular for hydrogen. In principle, however, pressure vessels formed in this way can also be used in all other fields of technology, for example as a stationary reservoir for the generation of energy in a fuel cell. Also, other gases can be filled with a suitable choice of material.
