基于虚拟试验环境下履带车辆滚动阻力系数的测试

Virtual Test of Tracked Vehicle Rolling Resistance Coefficient

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.

In this paper, the virtual test model of a high-speed tracked vehicle is established for testing rolling resistance coefficient; the model consists of a tractor and a tank, two rigid bars, measure equipment and constraint joints. Interactive force between high-speed tracked vehicle and rolling road is discussed, and the model of relationship between road property parameters and rolling resistance is established. By comparison with the test data, the feasibility of the model was verified.
