摘　　要：本文建立了惯导器件测试用精密离心机动平衡的动力学方程，给出了不平衡与电容测微仪输出振动位移之间的关系，得到了不平衡作用下精密离心机主轴几何轴线上各点运动方程及运动轨迹。The dynamical equation of dynamic balance system of the precision centrifuge for testing inertial navigation components has been established in this paper,and the relationship between the unbalance and the readout of the vibration displacement by the capacitive micrometer is given.Finally,the motion equation and locus of the geometric axis line of the main axis under the action of unbalance are acquired.
