通过对客车车身概念开发阶段有限元优化分析的作用和特点的研究,可以利用参数化分析模型进行早期结构方案优化分析,并针对实例客车概念开发,以提高整车刚度、降低车身骨架自重为目的,进行优化分析的应用研究。优化结果对于客车概念开发阶段的方案确定及后续车身结构详细设计具有重要参考。
Through the research on the function and characteristics of finite element optimization analysis of bus body conceptual development phase, the parametric analysis model can be used to optimize the early structural scheme. For the purpose of developing the bus concept, the purpose is to improve the rigidity of the vehicle and reduce the weight of the body frame , The application of optimization analysis. The optimization results have important reference for the plan determination of the bus concept development phase and the detailed design of the following body structure.
