空间光学组件的动力学环境试验

Environment experiment of dynamics of space optical subassemblies

动力学环境是空间光学遥感器及其组件研制中不可忽视的一个重要因素 ,因为它会对整机或组件造成结构性的破坏 ,所以在其研制的不同阶段须进行充分的动力学环境试验。空间光学系统是执行重要任务的子系统 ,在结构及其性能、工作精度要求、密封性、可靠性等方面均有比较特殊的要求。组件乃至系统不仅须经历动力学环境试验的严格考核 ,而且还须在此基础上通过其它相关试验做进一步的测试。针对空间光学组件及系统的特点和要求 ,对各种因素进行了综合研究并编制了各类组件的动力学环境试验大纲。同时 ,对试验中的控制、监测、试验夹具。

WT5BZ]Dynamics environment is a very important factor for the development of space optics remote sensors because it can bring about damage to the structure of the equipment and its subassemblies. For this reason, environment experiments of dynamics have to be adequately carried out during its different stages of the development. The space optics remote sensor, being a subsystem for executing significant task, has special requirements for its structure, behavior, operating precision, seal, reliability and so on. The whole equipment as well as its subassemblies have to be not only strictly examined through dynamics environment experiments, but also should be tested by other relevant experiments. According to their characteristics and conditions, an experiment document was worked out for the equipment and its subassemblies, and some technique issues and measures concerning control of vibration, inspection of response, linking jig, fixing of object tested, safety precautions in the experiment were analyzed and discussed.
