摘　　要：利用AN SY S软件建立了直升机某型动力传动轴和膜片联轴器的有限元模型,计算了其固有频率和模态振型,分析了膜片厚度对传动轴和膜片联轴器固有频率和模态振型的影响,计算结果为动力传动轴和膜片联轴器的动态设计提供了理论参考。Based on the ANSYS software ,the finite element model of a helicopter drive shaft and diaphragm coupling was developed. The natural frequency and mode of the drive system were obtained,and the affection of the thickness on the natural frequency and mode of the drive shaft and diaphragm coupling was analyzed, which provided the basis for the structural vibration and strength analysis of the drive shaft and diaphragm coupling transmission system.
