动平衡试验分子式：CAS号：性质：转子在专用的动平衡机上旋转以分别测定其两端面处振幅，惯性力和相位等参数，并在端面上进行去重或加配重的操作以达到最终消除振动的目的。转子长径比≥0.5，转数≥3000r/min或长径比≥1，转数≥700r/min时只做静平衡试验已不能奏效，必须代之以动平衡试验。其原理如图所示(图暂缺)。因转子较长(包括多叶轮串联的转子)重心点的轴向位置无法测定，加配重的操作又只能在端面上进行故出现了力矩。按静平衡方法加配重3与重力偏移惯性力相平衡(即F1=F3)，但F1和F3之间相距为a，故产生了使转子沿轴向断面翻转的惯性力矩F3·a。为此必须在两端面加不等的配重，以便同时达到惯性力和力矩的平衡和抵消。设转子质量M，重块3,4的质量m3，m4。于是(m3+m4)·R=Me，m3·R·a=m4R·b，从而求出m3和m4的大小。技术先进的动平衡机可直接读出m3·R和m4·R的数值以及点3和4的相位。如简易的动平衡机，需做许多加重量和加重点的试探才能最终确定。
