摘　　要：针对某工程用自卸车所配备的3种变速箱对整车性能的影响进行了对比,通过采用AVLCruise软件建立模型,分别分析了自卸车在不同速比情况下的爬坡性能,全负荷加速性能及燃油经济性,并对结果进行了综合分析,找出该自卸车较好的速比配置,最后在此基础上对各挡速比的敏感度进行了研究,为该自卸车的设计提供了参考依据。The comparison of the impact of three kinds of a dump truck gearboxes on vehicle performance is carried out,the model of dump truck is built by using AVL Crusise.The dumper at different ratio of climbing performance,full load acceleration performance and fuel economy are analyzed,and the results comprehensive analysis are carried out to find out the better ratio configuration.On this basis,the sensitivity of each gear ratio is studied and a reference to the design of the dump truck is provided.
