轨道车辆行李架托架的材料模型与实验修正

摘要

Taking the example of the luggage rack bracket, this paper uses the finite element method to check the strength of with bilinear elastoplastic model; then the stress distribution of luggage rack bracket is intuitively understood. Finally, it corrects the harden slope according to the experiment result and provides the basis for the subsequent analysis of the luggage rack bracket.%以行李架托架为例，采用双线性弹塑性模型，利用有限元方法对行李架托架强度进行了校核，比较直观地了解行李架托架的应力分布，并通过实验修正相关参数，为行李架托架后续分析提供了基础。
