用振幅测量原理研究机器刚性转子现场双面动平衡问题的新方法

本文提出了一种研究机器刚性转子现场双面动平衡问题的新方法,即双试重法。该方法与现有方法,即单试重法相比,所能提高的工作效率和降低的能源消托,均可达百分之四十以上。文中从振动的基本理论出发,详细地推导了加双试重测算转子双面动不平衡量大小和方向的计算公式,讨论了对不同支承形式的处理方法。用在动平衡机上的模拟对比实验和对现场的电机转子系统的平衡实例,证明了这一新方法的正确性。

A NEW METHOD OF RESEARCHINE THE SITE DUPLE FACE DYNAMIC BALANCE OF MACHINE RIGID ROTATOR BASE DON AMPLITUDE MEASUREMENT

In this paper, a new method of researching; the site dupleface dynamic balance of machine rigid rotator, namely duple test weightmethod is presented. Weight the new method against the existing method,namely single test weight method 1], both the efficiency increasing and theenergy-consumming dicreasing would be forty percent and over, with thebasic points of vibration theory, the formula of calculating weight andposition of the duple face dynamic unbalance of a rotator by means ofapplying the duple test weight is developed in detail. The method in handll-ing distinct bearing form is also discussed. Rightness of the new method isproved out by the living example of the simulant contrast testing carried outn the dynamic balance test machine and the site balance for a rotatorsystem of motor.
