摘　　要：结合某车最高车速试验结果与计算结果,得到了硬路面履带车辆行动系统阻力曲线,建立了行动系统阻力仿真模型,仿真计算结果与试验台架测试的行动系统阻力随车速的关系曲线基本一致,建立的行动系统阻力仿真模型可用于行动系统效率影响因素与车速的定量关系分析.建议将履带车辆运动方程中的车重与阻力系数乘积项统一称为运动阻力,可避免运动阻力、滚动阻力概念上的混淆.The track system resistance curve on hard pavement was given by the maximum velocity test results and simulation results. The simulation model of track system resistance was built. The curve about track system resistance and velocity of simulation results were basically in accord with the test results. The track system resistance simulation model can be used to analyze the relationship between the influence factors and velocity. The definition of moving resistance was suggested to replace the product of weight and resistance in motion equation to avoid the confusion of moving resistance and rolling resistance.
