| 摘 要： | 反射镜支撑结构通常需要具有一定的柔性来保证其面形精度,但这将引起结构固有频率降低,使得结构抵抗振动的能力下降.针对这一问题,开展了利用阻尼技术改善反射镜支撑结构动态性能的研究.建立了反射镜组件、相机机身和基础耦合的动力学模型,推导出系统传递函数、模态阻尼、振型等参数,并据此进行了理论分析.重点分析了在反射镜部分增加阻尼...

| Abstract: | To ensure the precision of the surface shape of the reflector,the supporting structure should be flexible.However,the natural frequency of the structure will be reduced by the flexibility,and hence the anti-vibration capability of the structure will be decreased.For solving this problem,the damping technology is introduced into supporting subassembly of reflector in this research.The dynamic model composed of the reflector subassembly,the camera block and the base is established.With the model,several param... |
