| 摘 要： | 为解决车辆负载过重问题，对铝合金栏板车车身及车架进行三维建模，利用HyperWorks 构建车身及车架的有限元模型。 模拟栏板车满载时的弯曲、扭转、紧急制动和紧急转弯4 种工况，施加相应的载荷与边界条件。 经过有限元仿真分析，获得了该车身(包括车架) 在不同工况下的应力分布状况，在存有较大设计余量的基础上，采用减薄壁厚和移动横梁的方法对车身结构改进。 结果表明:改进后的车身结构能够满足各典型工况的强度和刚度性能要求，质量比改进前减少了5.7%，从而为栏板车的结构设计和改进提供依据。

| Abstract: | In order to solve the problem of overload of the vehicle, 3D model of the body and frame of the aluminum alloy pallet car was built, and a finite element model of the body and frame was constructed with HyperWorks. After that, four working conditions of full-load bending, torsion, emergency braking and turning were simulated, and the corresponding loads and boundary conditions were applied. Consequently, the stress distribution of the body and the frame under different conditions was obtained through finite element analysis. Based on the existence of a large design margin, the method of thinning the wall thickness and moving the beams was used to improve the car body structure. Results show that the improved body structure can meet the strength and stiffness performance requirements of each typical working condition, and the mass is reduced by 5.7% compared with that before the improvement, thus providing a basis for the structural design and improvement of the pallet car. |
