【摘要】 本文首先运用HyperMesh对高速列车餐车车厢几何模型抽取中面,并在中面模型上剖分网格,建立以壳单元为主的有限元模型,然后将有限元模型导入Ansys进行静强度分析以及模态分析,最后将计算结果与有关规范进行对比,车体结构的静强度及刚度均满足要求。更多还原

【Abstract】 It uses the CAE software Hypermesh to extract the midsurface of the dining car model of high speed train,and then meshes the midsurface to obtain the finite element model which mainly consists of shell element. After that the finite element model is imported into Ansys to perform static strength and stiffness analysis,and by comparing the resultes with relevant design codes it comes to the conclusion that both the static strength and the stiffness of dining car meet relevant requirements.更多还原
