Paper Abstract

The bond stress is analyzed when the optics were attached to their mounts with high strength adhesive in space camera. The model was founded that a circular planar reflector supported by one, three, six or twelve adhesive points, which evenly distributed on different circles. The surface deformation of reflector is mainly caused by the shrinkage after solidity. The functional relation was deduced between the bonding force of the reflector and the characteristic dimension of the adhesive spot using piecewise function, and then analyzing the RMS error of no gravity assuming that the adhesive spot is fixed connect to the reflector using Nastran. The analytical RMS error was the aberration which added by solidification of adhesive. The calculation result is in good agreement with the experiment results. This analyzing method will be useful for the microstress clamping of high performance reflector system for application in space optical systems.
