摘　　要：采用有限元数值计算方法对液浮积分陀螺仪在过载-振动复合环境中的动力学特性进行研究。对液浮积分陀螺仪浮子组件谐态和模态进行了分析计算,获得了复合载荷下浮子组件质心的附加偏移的数据,从而为分析陀螺仪的附加误差提供了依据。The dynamic characteristic of the liquid floated integral gyro under over loading and vibration compound dynamical environment is studied by finite element method. The dynamic model and harmonic of the gyros floater components are analyzed. The additional excursion of centroid of the floater components is obtained. The reference data are offered to analyze the gyros additional errors.
