摘　　要：基于单面影响系数法,提出了一种动平衡测量方法。介绍了单面影响系数法的测量原理、整个测量系统的组成,并采用整周期采样法实现了对振动信号的提取。实验结果表明,该动平衡测量方法能够准确得出系统的动平衡量,对于消除旋转机构中的动平衡量具有一定的应用价值,也为其他场合下的动平衡测量提供了参考。The method for active balance meas- urement based on single - plane influence coeffi- cient method is described. The measurement prin- ciple of single- plane influence coefficient method, the composition of the entire measuring system and the signal extraction algorithm based on full -peri- od sampling method is given in detail. Experimen- tal results show that the active balance measure- ment method can obtain the magnitude and phase of active balance accurately. So this measurement method is of great value in eliminating the active balance in rotational mechanism, and can also serve as a reference when measuring active balance in other situations.
