精密离心机静偶不平衡分离的研究

分析惯导用精密离心机动平衡测试系统的测试信号；分别研究静不平衡与偶不平衡作用下转子的回转中心，分析静不平衡与偶不平衡的输出信号，求得静不平衡与偶不平衡，对干脆步平衡及偶不平衡分别在双校正面上进行了分离。解决由于测试点不在转子的支承处，所测得的振幅无法直接应用于静偶不平衡分离的力方程和力矩方程中的问题。

The Study on the Separation of the Static Unbalance and the Couple Unbalance in the Precision Centrifuge

The measurement signal of dynamic balance measuring system of an inertial navigation test equipment,the precision centrifuge,has been analyzed in this paper. The static unbalance and couple unbalance, their output signal, their separation on the two correction plane are all researched respectively. In the field of unbalance, the amplitude of the vibration cannot be applied to the force and the torque separation equation of the static unbalance and couple unbalance because the measurement point is not on the rotor support point, but this problem is solved in this paper.
