摘　　要：铁路重载运输是实现大宗重物运输的主要方式之一,货车结构的刚度、强度、稳定性的满足成为实现铁路重载运输的基本条件,而屈曲稳定性问题是比较特殊的,屈曲稳定性问题的发生往往是无征兆且瞬发的,一旦出现屈曲稳定性问题,会给结构带来极大的安全隐患。考虑到货车在运输过程中所承受的复杂工况,侧墙极大概率会发生屈曲现象,对复杂工况下散粒货车的侧墙进行了屈曲分析并对其进行形貌优化,以期提高侧墙的屈曲因子,从而提高其运行的稳定性。Railroad heavy transport is one of the main ways to realize the transportation of large quantities of heavy loads,stiffness,strength and stability of the wagon structure to meet basic conditions for the realization of the railroad heavy transport,and buckling stability problem is relatively special,the occurrence of buckling stability problem is often unsignalized and instantaneous,once buckling stability problem occurs,it will bring a great safety hazard to structure.Considering complex working conditions of truck in transportation process,the side wall will have a great probability of buckling phenomenon,the side wall of the bulk truck under complex working conditions has been analyzed and optimized to improve buckling factor of the side wall,so as to enhance the stability of its operation.
