摘　　要：文中对某多轴单纵臂车辆的行动部分进行了虚拟样机建模,依据总体任务指标及相关法规对其进行了不同制动强度工况下的制动过程仿真.通过对仿真结果的综合比较,分析得到了各轴在不同制动强度下轴荷动态分布特性,为车辆行动部件及车体的结构强度校核设计,以及各轴制动力的匹配优化设计提供了参考依据.This paper focuses on modeling the motion part of a specific multi-axis single trailing arm vehicle using virtual prototypes.Simulations of the braking process under varying intensities were conducted,guided by overall mission objectives and relevant regulations.A comprehensive comparative analysis of the simulation results yielded dynamic distribution characteristics of axle loads under varying braking intensities.This provides a reference for designing structural strength verification of vehicle motion components and body,as well as optimizing the matching of braking force for each axle.
