| 摘 要： | 利用ANSYS程序采用空间梁单元和薄壳单元,对某低入口城市客车车身结构的振动特性进行有限元分析。结果显示,当发动机在怠速工况时,它的振动频率接近于客车车身骨架的固有频率,易发生共振,应尽量避免。

| Abstract: | This paper discusses the vibrating performance of the body structure of a low-entrance city bus through ANSYS software based on the finite element analysis(FEA) with three-dimension beam elements and shell elements.The result shows that when the engine is in idling,its vibrating frequency is close to the natural frequency of the body frame.This will cause resonance effect and make passengers feel very uncomfortable.So this state should be avoided. |
