摘要
通过对轮轨接触几何关系和车辆动力学仿真计算结果进行对比,分析了车轮踏面外形对出口塞拉利昂窄轨矿石漏斗车动力学性能的影响,经综合考虑,建议出口塞拉利昂窄轨矿石漏斗车选用LM型踏面外形。
Via comparison in wheel-rail contact geometric relation and the calculation result of vehicle dynamics simulation,the effect of the wheel tread profile on the dynamics performance of narrow-gauge ore hopper cars exported to Sierra Leone is analyzed,through comprehensive consideration,the LM type tread profile is suggested to be used for the narrow-gauge ore hopper cars exported to Sierra Leone.
