通过建立履带车辆道路滚动阻力系数测试虚拟样机模型,在虚拟试验环境下测量了典型路面条件下的滚动阻力系数,研究了车辆行驶速度、履刺高度等因素对滚动阻力系数的影响。通过虚拟测试试验结果和实际测量结果的对比分析,验证了虚拟试验方法在道路滚动阻力系数测试中的可行性。
By establishing the road roller resistance coefficient test virtual prototype model of tracked vehicles, the rolling resistance coefficient under typical road conditions was measured in the virtual test environment. The influence of vehicle running speed, stab height and other factors on the rolling resistance coefficient was studied. Through the comparison and analysis of the virtual test results and the actual measurement results, the feasibility of the virtual test method in the road rolling resistance coefficient test is verified.
