基于Hypermesh的中型货车车架有限元分析与优化

针对某类型货车在使用中车架易形成疲劳破坏和断裂,进行了该型车架相关的刚度分析和强度分析。应用Hypermesh分析软件对车架有限元模型进行了模型的前后处理,得到车架在刚度与强度状况下的应力图和变形图。分析了车架的变形和应力状况,获得该类车架易受疲劳和强度破坏的薄弱环节,提出了合理的改进方案。通过车架改进前后的有限元分析比较,提出了车架的优化改进方案。

Finite Element Analysis and Optimization of Medium Truck Frame Based on Hypermesh

To the question of the medium truck frame which easily leads to endurance failure and breaking,made an analysis on the rigidity and intensity of the frame.It made a reasonable finite element model pre-and post-processing by Hypermesh and got the stress-strain diagram.It brought up a reasonable program of optimization and give the vulnerability of the frame and intensity of the weak links by analyze the deformation and strained conditions.It provided optimization program through improved pre-and post-frame finite element analysis.
