摘　　要：矿用自卸车多用于路面情况复杂,使用强度、载重强度大的矿山与大型工程建筑工地等工作环境恶劣的领域。目前,在冲击载荷与交变载荷矿山工况下使用时,为增加其强度、刚度,经常通过增加体厚度参数来达到其有足够的承载和抗冲击能力,但增加了整车质量。需对后桥壳进行合理的轻量化优化设计。本文运用UG与ANSYS有限元法软件对MT4400矿业自卸车后桥在满载静止、动载工况进行联合仿真分析,使其在满载静态和动态工况下质量减少率达12.7%及9.1%,实现了轻量化目的,具有广泛的实用性及应用价值。Mining trucks are used in areas where the road conditions are complicated and the working environment is harsh,such as mines and large-scale engineering construction sites with high strength and load strength.At present,in order to increase its strength and rigidity when used under impact load and alternating load mining conditions,the body thickness parameter is often increased to achieve sufficient bearing and impact resistance,but the quality of the whole vehicle is increased.It is necessary to carry out the reasonable lightweight and optimized design.This paper used UG and ANSYS finite element method to conduct a joint simulation analysis of the MT4400 mining truck under full-load static and dynamic conditions,so that its mass reduction rate reaches 12.7%and 9.1%under full-load static and dynamic conditions,achieving lightweight Purpose,has a wide range of practicality and application value.
