光学精密航天仪器运载中的环境振动试验研究

环境振动试验是鉴定结构或仪器设备能否承受预计的振动环境，保证在实际环境下结构的完整性或仪器设备性能、精度不降低的一种必要手段。文中对光学精密航天仪器在运载中的振动问题进行了研究，分析了不同路面、不同车速条件下运载光学精密航天仪器的随机振动响应，实验测量了多点的加速度信号，并用信号分析仪进行了数据处理，获得了该机振动的参数，为光学精密航天仪器的防振、抑振提供了参考。

Research on environment vibration experiment upon optical precision spaceflight apparatus during transportation

Environmental vibration can verify if engineering structure or instrument could endure predicted vibration environment.It is an essential means to ensure the structure integrity and maintain the instrument precision or performance under real environment.This paper gives an effective way of solving problems concerning vibration of the OPSA in vehicle transportation.The random vibration response of the OPSA during road transportation was analyzed under different road conditions and vehicle speeds.The acceleration signals at many points were tested,the data were processed using a signal analyzer and the OPSA's vibration parameters were obtained,which provides a reference for the OPSA anti-vibration and vibration reduction.
