阐述了用影响系数法做现场动平衡的基本原理及其计算方法 ,指出常规的带通方法对动平衡振动信号处理后确定的振幅和相位往往是不稳定的 ,同时提出了用相干平均的办法解决该问题。理论分析和现场实践均表明 ,这一方法是非常有效的。
The basic principles and calculation methods of dynamic balancing with the influence coefficient method are described. It is pointed out that the conventional band-pass method is unstable to the determined amplitude and phase after the dynamic balance vibration signal processing. At the same time, the method of coherent averaging Solve the problem Both theoretical analysis and field practice show that this method is very effective.
