Abstract
This paper describes the mechanical support developed by AMOS for the collimator that is used to perform some optical tests of the military satellite HELIOS. This support is computer controlled, class 100 clean environment compatible and can be used in high vacuum (10-6 mbar). Because of the specifications, static and dynamic analyses using finite element (FEM) method were necessary during the design phase. The final support is about 1 m high, 2.5 m long and 1.5 m across for a weight of about 1000 kg. It is able to rotate the collimator optical axis around a point with amplitudes of +/- 2.1 degree(s) and +/- 1.1 degree(s) in the vertical and horizontal planes respectively with a resolution of 1' and a repeatability of 2'.
