中型客车强度分析及试验研究

The Strength Analysis and Experimental Research of Medium Coach

从理论分析和试验两个方面全面评价了某中型客车的强度,论述了有限元模型(FEM)的建立过程及试验理论与方法.通过理论分析与实测数据的对比,表明两者结果具有较好的一致性,验证了有限元模型对实际车辆分析的准确性.利用准确的有限元模型及试验测得的数据,可以为该中型客车的轻量化提供依据.

A comprehensive evaluation of the ical analysis and test was given in this article. The well as the theory and method of the test was given. strength of the medium coach from the aspects of the theoret- process of the establishment of the finite dement model as Through the theoretical analysis and the measured data of the experiment, the results show that the results of FEM are well consistent with those of test so that the finite ele- ment model of the coach can give an accurate analysis of the medium coach. The accurate finite element model and the measured data can provide the basis and reference to the lightweight of this medium coach.
