基于子结构技术的光机装置反射镜组件的稳定性分析
Stability analysis of reflector module in the laser facility based on sub-structure method
摘要
Abstract
Reflector module is an important part of the laser facility, the rotation stability of which has a direct effect on the beam''s propagation.In order to obtain the rotations of reflectors due to ambient vibration, the finite element analysis is adopted.Finite model of a laser facility with mirror mount is built by the finite element analysis software based on full-structure and sub-structure methods.Then, the random vibration analysis is carried out, and the rotation angles of two reflectors are calculated.The result differences between these two methods are 3.99%,11.84%, which indicates that the analysis is reasonable based on sub-structure method when calculating the stability of large laser facility with mirror mount.关键词
