摘　　要：通过测绘建立电动轮自卸车车厢结构的三维实体模型,采用壳单元、焊接单元和实体单元实现车厢结构的有限元网格划分,在归纳车厢工作载荷特征的基础上,建立了车厢结构有限元模型。针对典型载荷工况对车厢结构进行了有限元分析,获得了车厢结构的应力场和位移场分布,计算结果符合车厢使用损坏情况,对车厢的结构改进与制造维修具有指导意义。The CAD model is built by mapping the structure of the track＇s body. The body structure is meshed with shell element, weld element and solid element. The finite element modeling of the loading cases are built by studying the employment characteristic of the truck. The finite element analysis on track structure for the representative loading case is made and the distribution of the stresses and the displacements of the body are obtained. Numerical results conform to the practical utilization of track, thus providing a guiding meaning for improving and maintaining the tracks.
