根据高精密光学系统的工作环境条件, 即要求车载光学平台具备良好的力学性能和隔振性能, 制定了车载光学平台的结构设计方案。通过ANSYS对车载光学平台进行了静态、模态分析, 获得静态应变及振动模态, 从而对车载光学平台进行优化设计。车载光学平台随载车进行了跑车试验和测试, 结果显示, ANSYS仿真分析结果与测试结果相近, 表明车载光学平台具有良好的稳定性, 保证高精密光学系统能够稳定工作。

According to working conditions and the requirements of better mechanical and vibration isolation properties, the structure design scheme of a vehicular optical platform is established. Static and modal analysis of the platform is performed by ANSYS to obtain static strain and vibration mode, and the optimum design is performed. The vehicular optical platform is tested on the vehicles, and the results show that the simulation results of ANSYS are close to the testing results. It is shown that the vehicular platform has better stability to ensure stable working state of the high precise optical system.
