摘　　要：激光器壳体作为激光器光路固定的重要功能构件,对激光器的光束稳定性及光斑质量、系统效率起到关键作用。基于ANSYS Workbench软件对激光器壳体进行静、动态特性分析,确定模态频率与结构振型之间关系,得到壳体薄弱环节。通过增加筋板结构对激光器壳体进行优化,优化结果显示,静态综合变形量减小23.9%,最大应力减小15.8%,各阶固有频率有所提升,平均增幅为15.9%,结构优化良好,为后期激光器设计优化提供了参考。As an important functional component of the laser optical system,the laser support structure plays a key role in the Laser beam quality,stability and system efficiency of the laser.The static and dynamic characteristics of Laser support structure were analyzed based on ANSYS Workbench.The relationship between the modal frequency and the structural mode were determined,and the weak part of the shell was obtained.The laser shell is optimized by adding the stiffened plate.The optimization results show that the total deformation is reduced by 23.9%,the maximum equivalent stress is reduced by 15.8%,the natural frequency of each mode is improved,the average increase is 15.9%。The optimization of structure has obtained the good effect.The result provides a reference for later design optimization of laser design.
