提出了一种新的转子动平衡原理与方法——动刚度系数法，它可自动计算出支承系统在若干转速下的瞬态动刚度系数和阻尼系数，并求出所需配重，经１～２次配重，即可完成平衡。为此采用了锁相环电路和自动跟踪滤波电路，智能以八位单片机８０５１为核心，以十二位的高速数模转换芯片ＡＤ５７４为基础，设计一套智能电测系统。该系统具有自动控制模拟电路的传递函数，对数据可进行自动采集、处理和存储，经通讯口送入主机内，使主机具有多种智能化功能
A new principle and method of rotor dynamic balancing - dynamic stiffness coefficient method is proposed. It can automatically calculate the transient dynamic stiffness coefficient and damping coefficient of the bearing system under several rotating speeds and find the required counterweight. After 1 ~ 2 times the weight, you can complete the balance. To this end, a phase-locked loop circuit and an automatic tracking filter circuit are adopted. The intelligent 8051-based microcontroller takes the 12-bit high-speed digital-analog conversion chip AD574 as its basis and designs a set of intelligent electrical measuring system. The system has automatic transfer function control analog circuit, the data can be automatically collected, processed and stored in the host through the communication port, the host has a variety of intelligent features
