液浮陀螺仪框架结构刚度特性的研究

A Study on the Stiffness Performance of Liquid Floated Gyroscope Frame Structure

本文用有限元数值计算方法对引起液浮陀螺仪 b2 项漂移的陀螺仪框架结构 X、Y方向的刚度特性进行了分析 ,给出了三类框架模型在不同载荷作用下所表现出来的柔度特性 ,并对陀螺仪框架进行了结构优化 。

The stiffness performance in X,Y orientation of gyroscope frame was analyzed using FEM in this paper.It is the main reason which causes the drift of liquid floated gyroscope.We also give the flexible property of three types of frame model under different loads.Further more,the structure of gyroscope frame was optimized.The results provide an important reference for improving the design of the gyroscope.
