摘　　要：对某壳式乘用客车车身骨架进行有限元静态分析,通过建立包含悬架系统的车身模型并使用普通计算方法进行仿真分析,与不含悬架系统的车身模型使用惯性释放的方法进行仿真分析对比,发现惯性释放方法有一定的缺陷,认为普通计算方法更有优势。The authors make a finite element static analysis on a shell type bus body frame. They make the simulation analysis through establishing the body model containing the suspension system by using common calculation method, and another simulation analysis on the body model with no containing suspension system by using the inertial release method. Through the above two analysis methods comparison, they find the inertial release method has certain defects, and think the common calculation method has more advantages.
