摘要
由于客车车身刚度是评价客车车身性能的一项重要指标,因此,文章采用梁体混合模型的方法,建立了一款半承载式客车的有限元模型。利用有限元方法分析了客车车身在不同工况下的刚度,通过静态刚度的分析,对客车中门进行了改进,并为整个车身结构的优化提供了依据。
The rigidity of the bus body, which is an important index in assessing its performance, is studied. By using finite element software, the rigidity of a bus body in different working conditions is analyzed,and three plans for improvement of the middle door are presented and compared, and as a result,the third plan is considered to be the best. This study provides a basis for optimization of the whole structure of the bus body.
