摘　　要：膜片联轴器在直升机尾传动轴和动力传动轴安装中应用广泛,通过建立简化后的有限元模型,并进行精细化网格划分,基于其实际工况同时考虑离心力作用,用ANSYS Workbench进行有限元仿真并计算得到膜片联轴器的径向、轴向、扭转和转角刚度特性参数。通过对比施加离心力和不施加离心力两种情况下的各项刚度,结果表明:膜片联轴器在径向、轴向和扭转方向刚度较大,可提供较好的补偿作用;离心力对膜片联轴器轴向刚度和转角刚度影响较大,在进行高速运转机械各项刚度计算时应该考虑,对后续传动轴动力学建模具有一定的参考意义。Diaphragm coupling has been widely used in the installation of the tail drive shafts and the MGB drive shafts,based on the actual working conditions and considering the centrifugal force,the simplified finite element model is established and the fine mesh is divided,and the ANSYS Workbench is used to simulate and calculate the stiffness characteristic parameters of the diaphragm coupling in radial,axial,torsional,and angular directions.By comparing the stiffness in all directions of applying centrifugal force and not,the results show that diaphragm coupling has higher stiffness in radial,axial,and torsional directions which can provide better compensation and the centrifugal force has a great influence on the axial stiffness and angular stiffness of the diaphragm coupling,and it should be considered when calculating the stiffness of high-speed rotary machine,which has a certain significance for the subsequent dynamic of the transmission shafts.
