波前校正器应用于空间光学系统必然要经历卫星动力学环境,随机振动环境是其中一个很重要的影响因素。采用有限元方法分析两种波前校正器在随机振动环境中的应力分布,结果表明所受应力均小于其材料的许用应力,器件结构未受破坏。随后对器件进行随机振动试验。试验后器件的几种主要性能均未受到影响,说明器件可承受均方根为6g的随机振动环境。
The application of wavefront corrector to space optical system is bound to experience satellite dynamic environment. Random vibration environment is one of the most important factors. The finite element method is used to analyze the stress distribution of the two wavefront correctors in a random vibration environment. The results show that the stress is less than the allowable stress of the material, and the structure of the device is not damaged. The device was then subjected to a random vibration test. After the test several of the main performance of the device were not affected, indicating that the device can withstand a random vibration environment root mean square 6g.
