摘要
应用有限元前后处理软件Patran对车身骨架进行有限元建模,然后导入MSC.Nastran进行无阻尼自由振动状态下的模态研究,得到该校车车身骨架结构有限元模型的模态,并对得到的理论模态参数进行分析,为该车车身骨架的设计方案提供全面的评价。
The finite element modeling for auto- body structure was carried out with the help of pre and post processing software for finite element-Patran. The solution of modal analysis to the model in undamped free vibration was performed with MSC. Nastran and the post processing analysis of the calculated result was carried out with Hypermesh. Based on the finite element analysis of school bus＇ body structure,a comprehensive evaluation and improvement for the design of the car body frame was provided.
