A disclosed arc-shaped light-weight cargo compartment is used for a dumper and is of a structure formed by splicing four assemblies, the length, the width and the height of each assembly are within the transportation requirement range (14*3.5*4.5 m), and the problems of ultra-wide transportation and ultra-high transportation are solved. Large circular arc transition is adopted among a bottom plate, side plates and a front plate, corner stress concentration and material accumulation are avoided, the overall ductility is good, and the impact resistance is high; the tail of the cargo compartment is of an arc structure, an actual material stacking model is met, the tail of the cargo compartment cannot touch a cab framework firstly when a vehicle is in rear-end collision, and operation safety is high; and through finite element analysis and discrete element analysis, the structural form and groove rib arrangement are optimized, the dead weight of the cargo compartment is reduced, and meanwhile the service life is prolonged.

    本发明公开了一种圆弧形轻量化货厢,用于自卸车,采用四个组件拼接结构,各组件长宽高均在运输要求范围之内(14*3.5*4.5m),避免了运输超宽、超高的问题;底板与侧板、前板之间采用大圆弧过渡,避免边角应力集中、物料堆积,整体延展性好,抗冲击能力强;尾部采用圆弧结构,符合实际的物料堆装模型,且当车辆追尾时,货厢尾部不会先碰触驾驶室骨架,运行安全性高;通过有限元分析及离散元分析,优化结构形式和槽筋布置,降低了货厢自重的同时提升了使用寿命。
