摘　　要：利用ANSYS对膜片弹簧进行非线性有限元分析得到的弹性特性曲线与经验公式计算的曲线相当吻合,且更为贴近实验曲线;同时对膜片弹簧的工作全过程的应力变化进行了模拟,以对膜片弹簧的设计提供指导。In this paper, the characteristic curves of diaphragm spring using nonlinear FEM in ANSYS are consistent with the ones based on Almen-Laszlo formulae, and more adjacent with the experimental curves;in addition, the simulation of diaphragm spring＇ s stress change in working condition is described which provide the guidance of spring＇s design.
