| 摘 要： | 按照美国AAR标准，利用有限元软件ANSYS对40t轴重不锈铜矿石专用敞车车体进行了非线性屈曲分析。文章主要考虑几何非线性，采用增量法对地板有无拱筋的2种车体模型进行分析计算，通过计算结果对比，发现地板上加拱筋不仅提高了车体的强度，还可以增强地板的刚度，使车体在规定栽荷内不发生屈曲，提高车体的稳定性。

| Abstract: | According to AAR Standard in America,with the finite element software ANSYS,the non-linear buckling analysis is made for the stainless steel carbody of the special gondola car for ore with an axle-load of 40 t.The geometric non-linearity is mainly considered in this paper.The incremental method is used to make the analysis and calculation of two kinds of carbody models in which the floor is with and without arch tendon.It is proved through comparison of the calculation results that the arch tendon in the fl... |
