客车车身骨架的有限元分析

Finite Element Analysis for Bus Body Structure

以客车的车身骨架为研究对象,采用有限元分析的方法对其进行静强度分析和模态分析。在研究过程中,采用Pro/E软件建立车身骨架的三维几何模型,再以ANSYS软件进行静强度分析和模态分析。以“威尼斯之旅”车身骨架为例,对其进行了静强度和模态分析;指出了该车的车身骨架在设计中可能存在的问题,针对这个问题提出了改进方案,并取得了较好的效果。

Bus body structure is analyzed in this paper by using FEA. The software Pro/E is employed on building three-dimensional geometry modal and static strength analysis and modal analysis are put up with ANSYS during the research. In this paper, the Venice Travder is taken as an example for analyzing static strength and modal. The problems in the body structure design are pointed out. The modification design of body structure is presented, and good effect has been accomplished.
