摘要
建立了激光陀螺抖动系统的三维有限元模型,对其振动特性进行了模态分析,并对该系统进行了模态实验测量,最后将模态分析的结果和实验测量结果进行了对比。对比结果表明,所建立的有限元模型合理,分析结果可靠,对该系统的改进设计具有重要意义。
The 3D finite element modal of dithering system of laser gyroscope is constructed in this paper, and the modal analysis for its vibration characteristic is performed. The modal test for the system is made, and the two results obtained above are compared. The accordance of the two results reveals that the finite element modal constructed in this paper is rational, and the analysis result is reliable. It is very helpful for improving the design of the system.
