摘要：

In space optical remote sensor, the relative position and orientation of primary mirror and secondary mirror have important influence on high quality imaging. Adjusting the secondary mirror pose is one of the means to improve the imaging quality of space camera. In order to meet the requirements of secondary mirror pose adjustment and improve the performance and economy of the mechanism, the Stewart platform, a typical kind of 6-DOF parallel mechanism, is optimized. Firstly, a parametric model of the Stewart platform is established in ADAMS. Secondly, the optimal objective function of the Stewart platform is established. Thirdly, According to the actual constraint conditions, the constraint function is set up. Finally, the ADAMS simulation software is used to add objective function and constraint functions to optimize the structure parameters and optimized structural parameters are obtained. After parameter checking, all indexes of the optimized secondary mirror positioner meet the requirements.
