摘　　要：针对某矿用汽车,通过理论分析结合工程实践经验的方法,确定整车制动力及分配。采用多体动力学模型仿真计算的方法,分析前、后制动力分配系数对整车制动性能的影响。仿真结果表明,当制动力分配系数为0.6时,能够较好地兼顾车辆的制动效能及制动时的方向稳定性,进一步说明理论分析确定的整车制动力及其分配基本最优。For a mining truck,the overall brake force and distribution are determined through theoretical analysis and engineering practical experience.The method of simulation and calculation of the multi-body dynamics model is used to analyze the inf luence of front and rear brake force distribution coefficients on the overall brake performance.The simulation results show that,when the distribution coefficient of the brake force is 0.6,it can better balance the brake efficiency of the vehicle and the directional stability during braking,which further indicates that the overall brake force and its distribution determined by theoretical analysis are basically optimal.
