摘要
为了得到某种客车车架的静态和动态特性,运用有限元软件建立了该种车架的模型,并对该车型车架进行了静力学分析及模态分析,从而得到了车架的变形、应力分布及其固有频率和振型。据此,提出了几种该种车架机构上的改进方案。研究分析结果表明,该方法为进一步改善该车架的结构提供参考。
Aiming at getting the static and dynamic characteristics of a bus frame, the model was firstly investigated by the means of finite element software. The frame＇s displacement distribution and stress distribution and the inherent frequencies and vibration modes were reported after being analyzed. Based on these, some improvements were proposed. The analysis results show that it can provide the reference of optimizing the frame＇s structure.
