后空气悬架半承载式与全承载式车架有限元对比分析

摘要

Based on the CATIA software, the same length of the semi-integral and monocoque chassis frame of the rear air suspension of the 12 meters bus is modeled. Finite element comparative analysis of the two types of chassis frame located at the rear air suspension under various conditions of the stress distribution, deformation and the ad-vantages and disadvantages are carried out.%基于CATIA软件，对12 m客车取安装后空气悬架处半承载式与全承载式车架等长度建模，进行有限元对比分析后空气悬架处两种车架在多种工况下的应力分布、变形情况及优缺点。
