| 摘 要： | 文章在建立半承载式车身骨架板梁有限元模型的基础上,对车身骨架的强度、动态(模态)性能进行分析及静动态强度试验,建模中采用变截面梁,以便真实地模拟车身受力情况;结果表明有限元模型精度较高,骨架强度满足要求,存在优化空间,为轻量化提供参考依据。

| Abstract: | The finite element(FM) models of the beams and plates and the FM model of the whole vehicle are established.Strength and modal analysis of the frame is carried out based on experiments and calculations.The static strength test results prove that the FE model has good analytical precision.The strength of the frame meets the requirements,and the bus body structure can be lightened further. |

| Keywords: | semi-integral bus body finite element method strength analysis modal analysis strength test |
