This paper applies FEM, taking a U-shaped bellow for example, toestablish the finite element model, and carry through modal analysis to simulateits natural frequency and vibration mode with different parameters.

• 本文在总结波纹管常规分析方法的基础上,运用有限元分析和计算的方法,以某一U型波纹管为例,建立了参数化的有限元模型,并对不同参数下的模型进行模态分析仿真出固有频率和振型;
