摘　　要：介绍3种曲轴转子不平衡力的计算方法,并得出该3种方法可以相互佐证其计算正确性,利用上述结论运用方法二(Motion运动分析法)分析4M型曲轴动平衡性能。这种方法可以在曲轴设计前期就可以对曲轴进行动平衡分析,提高曲轴设计精度、降低机组振动,缩短曲轴开发周期。This paper introduced three types of calculation methods of unbalanced forces for crankshaft rotors,and concluded that three types of methods can prove its correctness of each other. This paper used No.2 method(Motion Analysis) to analyze the dynamic balance performance of 4 M crankshafts. This method can perform dynamic balance analysis on the crankshaft in the early stage of crankshaft design, which could improve the design accuracy for crankshaft, reduce the equipment vibration, and shorten the crankshaft development period.
