Abstract

A mounting for an astronomic mirror (41) has several mounting elements (48, 49; 50, 51) arranged underneath the bottom side of the mirror. The lines of application of the mounting elements run through the general centre of gravity of the mirror and the mirror (41) is secured against rotation and axial lateral displacements. At least three dimensionally stable auxiliary structures (44, 45) without thermal deformation in the plane (52) of the centre of gravity are arranged between the mirror and the mirror mounting elements. The auxiliary structures are directly secured to the mirror (41) to be supported and three actuators (48, 49; 50, 51) are arranged between the mirror mounting elements and each auxiliary structure.

Lagerung für einen astronomischen SpiegelStorage for an astronomical mirror
Die Erfindung betrifft eine Lagerung für einen astronomischen Spiegel mit mehreren unterhalb der Spiegelunterseite angebrachten Halterungselementen, bei welcher die Wirkungslinien der Halterungselemente durch den Gesamtschwerpunkt des Spiegels gehen und bei welcher der Spiegel sowohl axial lateral und rotationssicher gelagert ist.The invention relates to a mounting for an astronomical mirror with a plurality of mounting elements attached below the underside of the mirror, in which the lines of action of the mounting elements pass through the overall center of gravity of the mirror and in which the mirror is mounted both axially laterally and in a rotationally secure manner.
Astronomische Spiegellagerungen koppeln die Spiegelzelle und den Spiegel mit sechs Freiheitsgraden und bestehen im allgemeinen aus einem axialen Supportsystem, welches die Hauptlast des Spiegels trägt, zwei lateralen Supportsystemen, welche zueinander und zum axialen System senkrecht angeordnet sind und einem Drehsicherungssystem. Die beiden lateralen SupportSysteme haben meist nur die halbe Anzahl von Stützpunkten des axialen und sind so angeordnet, daß ihre Wirkungslinien durch den GesamtSchwerpunkt des Spiegel gehen, um keine Momente im Spiegelkörper entstehen zu lassen. Eines der beiden lateralen Systeme ist seinerseits in zwei Teilen ausgeführt, um gemeinsam den Rotationsfreiheitsgrad abzudecken.Astronomical mirror bearings couple the mirror cell and the mirror with six degrees of freedom and generally consist of an axial support system, which bears the main load of the mirror, two lateral support systems, which are arranged perpendicular to each other and to the axial system, and an anti-rotation system. The two lateral support systems usually only have half the number of axial support points and are arranged in such a way that their lines of action go through the entire center of gravity of the mirror so that no moments occur in the mirror body. One of the two lateral systems is designed in two parts to jointly cover the degree of freedom of rotation.
Alle Lagerungskräfte sind einzeln am Spiegel angekoppelt und werden so miteinander kombiniert, daß keine Kopplungen mit mehr als sechs Freiheitsgraden zwischen Spiegel und Zelle entstehen.All positioning forces are individually coupled to the mirror and are combined with one another in such a way that there are no couplings with more than six degrees of freedom between the mirror and the cell.
Derartige Spiegellagerungen sind z.B. bekannt aus der DE 36 03 217 und der EP 0 317 493.Such mirror bearings are e.g. known from DE 36 03 217 and EP 0 317 493.
Es ist die Aufgabe der Erfindung eine Spiegellagerung zu schaffen, bei welcher alle drei orthogonalen Raumrichtungen mit der gleichen Anzahl von Stützpunkten ausgestattet und somit untereinander völlig gleichwertig sind.It is the object of the invention to provide a mirror mounting in which all three orthogonal spatial directions are equipped with the same number of support points and are therefore completely equivalent to one another.
Diese Aufgabe wird erfüllt durch den kennzeichnenden Teil des ersten Patentanspruchs . Die Erfindung wird ermöglicht durch eine metallische Hilfsstruktur, die aufgrund ihrer thermischen Eigenschaften direkt an drei Punkten mit dem Spiegel verklebt werden darf. Diese ist aus der DE 29 603 024 bekannt. Wenn an einem Spiegel mindestens drei solche Strukturen befestigt sind, lassen sich an jeder Hilfsstruktur drei zueinander orthogonale Freiheitsgrade so kombinieren, daß alle Wirkungslinien durch einen Teilschwerpunkt des Spiegels verlaufen.This object is achieved by the characterizing part of the first claim. The invention is made possible by a metallic auxiliary structure, which due to its thermal properties can be glued directly to the mirror at three points. This is known from DE 29 603 024. If at least three such structures are attached to a mirror, three mutually orthogonal degrees of freedom can be combined on each auxiliary structure in such a way that all lines of action run through a partial center of gravity of the mirror.
Im Gegensatz zum Stand der Technik sind hier alle drei orthogonale Raumrichtungen mit der gleichen Anzahl von Stützpunkten ausgestattet und somit untereinander völlig gleichwertig. Jede der drei Raumrichtungen unterstützt dabei einen Teilschwerpunkt des Spiegels, der seinerseits durch den Schwerpunkt der drei Befestigungspunkte der Hilfs truktur gemeinsam mit dem Schwerpunkt der Hilfsstruktur selbst definiert wird.In contrast to the prior art, all three orthogonal spatial directions are equipped with the same number of support points and are therefore completely equivalent to one another. Each of the three spatial directions supports a partial focus of the mirror, which in turn is defined by the focus of the three attachment points of the auxiliary structure together with the focus of the auxiliary structure itself.
Werden beispielsweise sechs Hilfsstrukturen mit dem Spiegel verklebt, so ergeben sich 18 Lagerungspunkte zwischen dem Spiegel und den sechs Hilfsstrukturen, aber nur sechs Punkte pro Raumrichtung für das- gesamte SupportSystem. Von diesen insgesamt 18 Lagerungspunkten werden sechs durch feste Verbindungen verifiziert, welche voneinander unabhängig gewählt werden müssen, damit die erforderlichen sechs Freiheitsgrade der Kupplung zwischen Spiegel und Zelle entstehen. Die übrigen 12 Lagerpunkte werden mit Kraftaktuatoren bestückt, nach bewährtem hydraulischen oder mechanischen Konzept. Somit we.rden nur 12 aktive Supportaktuatoren benötigt, gegenüber 18 axialen plus 2 x 9 lateralen einer herkömmlichen hydraulischen Lagerung. Diese Reduktion des Aufwandes um den Faktor drei ist der Kernpunkt der Erfindung die durch die dimensionsstabile Hilfsstruktur ermöglicht wird.If, for example, six auxiliary structures are glued to the mirror, there are 18 bearing points between the mirror and the six auxiliary structures, but only six points per spatial direction for the entire support system. Of these 18 storage points in total, six are verified by fixed connections, which must be selected independently of one another so that the required six degrees of freedom for the coupling between the mirror and the cell arise. The remaining 12 bearing points are equipped with force actuators, based on the proven hydraulic or mechanical concept. This means that only 12 active support actuators are required, compared to 18 axial plus 2 x 9 lateral of a conventional hydraulic bearing. This reduction of the effort by a factor of three is the central point of the invention which is made possible by the dimensionally stable auxiliary structure.
Die Erfindung wird im folgenden in beispielhafterweise anhand von Zeichnungen erläutert, wobei weitere wesentliche Merkmale sowie dem besseren Verständnis dienende Erläuterung und Ausgestaltungsmöglichkeiten des Erfindungsgedankens beschrieben sind.The invention is explained in the following by way of example with reference to drawings, further essential features and explanations and for better understanding Design options of the inventive concept are described.

Eine spannungsfreie Lagerung (wie sie z.B. aus der DE 296 03 024 bekannt ist) kann insbesondere sehr vorteilhaft zur Lagerung eines astronomischen Spiegels verwendet werden, wie dies in Figur 1 dargestellt ist.Stress-free storage (as is known, for example, from DE 296 03 024) can be used very advantageously for mounting an astronomical mirror, as shown in FIG. 1.
Mit der erfindungsgemäßen spannungsfreien Lagerung ist es nun möglich eine Spiegellagerung zu schaffen, bei welcher alle drei orthogonalen Raumrichtungen mit der gleichen Anzahl von Stützpunkten ausgestattet und somit untereinander völlig gleichwertig sind.With the tension-free mounting according to the invention it is now possible to create a mirror mounting in which all three orthogonal spatial directions are equipped with the same number of support points and are therefore completely equivalent to one another.
Die spannungsfreie Lagerung kann auf Grund ihrer thermischen Eigenschaften direkt an drei Punkten mit dem Spiegel verklebt werden (44, 45 in Figur 1, dritter Lagerungspunkt ist in der Figur nicht dargestellt) . Wenn an einem Spiegel (41) mindestens drei solche Strukturen (44, 45) befestigt sind, lassen sich an jeder spannungsfreien Lagerung drei zueinander orthogonale Freiheitsgrade so kombinieren, daß alle Wirkungslinien durch einen Teilschwerpunkt des Spiegels (41) verlaufen.Due to its thermal properties, the stress-free mounting can be glued directly to the mirror at three points (44, 45 in FIG. 1, the third mounting point is not shown in the figure). If at least three such structures (44, 45) are attached to a mirror (41), three degrees of freedom that are orthogonal to each other can be combined on each tension-free mounting such that all lines of action run through a partial center of gravity of the mirror (41).
Der in der Figur 1 dargestellte astronomische Spiegel (41) besitzt an seiner Unterseite dimensionsstabile Hilfsstrukturen (44, 45), welche auch als spannungsfreie Lagerungen bezeichnet werden. Der Spiegel (41) ist in dem hier dargestellten Beispiel ein Leichtgewichtspiegel, welcher eine geschlossene, verspiegelte Oberfläche (41.1) und eine geschlossene, ebene Spiegelunterseite (41.2) besitzt. Diese beiden äußeren Flächen sind durch Rippen (41.3) stabil miteinander verbunden. In seiner Mitte besitzt der kreisrunde Spiegel (41) eine Öffnung (42) . Der Spiegel (41) ist in einer gekippten Lage von 42,5° relativ zum Horizont dargestellt.The astronomical mirror (41) shown in FIG. 1 has dimensionally stable auxiliary structures (44, 45) on its underside, which are also referred to as stress-free bearings. In the example shown here, the mirror (41) is a lightweight mirror, which has a closed, mirrored surface (41.1) and a closed, level surface Has the underside of the mirror (41.2). These two outer surfaces are connected to each other by ribs (41.3). The circular mirror (41) has an opening (42) in its center. The mirror (41) is shown in a tilted position of 42.5 ° relative to the horizon.
Die dimensionsstabilen Hilfsstrukturen (44, 45) sind über Verbindungen (48, 49, 50, 51) mit der Spiegelzelle (43) verbunden. Am bzw. im Spiegelkörper (41) selber sind sie an den entsprechenden Punkten (46) direkt angebracht, wobei der Befestigungspunkt in der Schwerpunktebene (52) des SpiegelsThe dimensionally stable auxiliary structures (44, 45) are connected to the mirror cell (43) via connections (48, 49, 50, 51). On or in the mirror body (41) itself, they are attached directly to the corresponding points (46), the attachment point in the focal plane (52) of the mirror
(41) liegt. Jede der dimensionsstabilen Hilfsstrukturen (44, 45) ist hier im oberen Teil (44') aus Titan und im unteren Teil(41) lies. Each of the dimensionally stable auxiliary structures (44, 45) is made of titanium in the upper part (44 ') and in the lower part
(44'') aus Aluminium aufgebaut. Entlang der Trennungslinie (47) kann der Spiegel (41) von der Spiegelzelle (43) getrennt werden. Der thermische Ausdehnungskoeffizient o.ι_ des Spiegels(44 '') made of aluminum. The mirror (41) can be separated from the mirror cell (43) along the dividing line (47). The thermal expansion coefficient o.ι_ of the mirror
(41) muß dabei nicht dem thermischen Ausdehnungskoeffizienten C-2 der Spiegelzelle (43) entsprechen.(41) does not have to correspond to the thermal expansion coefficient C-2 of the mirror cell (43).
Außer den beiden in der Figur dargestellten Verbindungen (44, 45) besteht noch eine dritte Verbindung zu jeder der dargestellten dimensionsstabilen Hilfsstruktur (44, 45).In addition to the two connections (44, 45) shown in the figure, there is a third connection to each of the dimensionally stable auxiliary structures (44, 45) shown.
Die in der Figur 1 dargestellten Verbindungen (48, 49; 50, 51) sind Aktuatoren, welche mechanischer oder hydraulischer Art sein können. Die Verbindungen (48, 49; 50, 51) einer dimensionsstabilen Hilfsstruktur (44, 45) erzeugen jeweils einen Teilschwerpunkt (471, 471'), welcher in der Schwerpunktebene (52) liegt.The connections (48, 49; 50, 51) shown in FIG. 1 are actuators, which can be mechanical or hydraulic. The connections (48, 49; 50, 51) of a dimensionally stable auxiliary structure (44, 45) each produce a partial center of gravity (47 1 , 47 1 '), which lies in the focal plane (52).
In der Figur 2 ist ein Spiegelunterstützungssystem beschrieben welches sechs dimensionsstabile Hilfsstrukturen verwendet, welche hydrostatische Aktuatoren haben. In dieser Figur 2 sind die jeweils einen Freiheitsgrad unterstützenden SupportSysteme jeweils mit der gleichen Nummer gekennzeichnet.FIG. 2 describes a mirror support system which uses six dimensionally stable auxiliary structures which have hydrostatic actuators. In this FIG. 2, the support systems that support one degree of freedom are each identified by the same number.
Die sechs Freiheitsgrade sind so verteilt, daß in der Hauptlastrichtung (z.B. bei der Verwendung der Lagerung in einem Flugzeug) drei hydraulische Kreise mit den Aktuatorpaaren (61'', 62'') und (63''). In der ersten lateralen Richtung wirken die beiden Kreise (64'') und (65''); in der zweiten lateralen Richtung wirkt dann nur noch ein Kreis (66' ') . The six degrees of freedom are distributed so that in the main load direction (e.g. when using the bearing in one Airplane) three hydraulic circuits with the actuator pairs (61 '', 62 '') and (63 ''). The two circles (64 ″) and (65 ″) act in the first lateral direction; only a circle (66 '') then acts in the second lateral direction.
