摘　　要：为了检测硬支承情况下转子的不平衡量,针对目前常用相敏检波电路的缺点,提出了一种模拟乘法器式检测转子旋转过程中不平衡量大小和相位的相敏检波法。描述了此方法的原理,运用此方法设计了检测电路,实现了预期的目的。In order to measure the dis - equilibrium amount of stiff support, aimed at the circuit shortcoming of phase sensitive demodulation, one kind of dis - equilibrium amount and phase examination method based on simulation multiplier is proposed in this paper. The principle is explained, and this method is designed to exam electric circuit and has realized anticipated goal.
