摘要: 以装用转K6型转向架的C80型货车为例, 在SIMPACK软件中建立车辆动力学模型, 采用LM型车轮型面和75 kgºm-1级钢轨型面匹配, 并根据大秦线实际情况建立线路模型。基于FASTSIM算法和Zobory踏面磨耗模型, 对重载货车车轮磨耗进行仿真分析, 并与现场实测结果进行对比。研究结果表明: 磨耗主要发生在踏面上-50~45 mm范围内, 轮缘处磨耗最大, 在轮缘根部磨耗最小; 随着运营里程的增加, 轮缘和滚动圆处的磨耗速度变慢; 踏面垂直磨耗量的仿真结果小于现场实测结果; 车轮磨耗后, 车辆临界速度下降, 空车临界速度下降13~18 kmºh-1, 重车临界速度下降2~8 kmºh-1。Abstract: The dynamic model of C80 heavy haul freight car with ZK6 bogies was built in SIMPACK software, LM wheel profile and 75 kgºm-1 rail profile were matched, and a railway line model was built based on Daqin Railway Line. The wheel wear of heavy haul freight car was simulated based on FASTSIM algorithm and Zobory tread wear model, and the simulation results were compared with that of field test result. Analysis result indicates that wear occurs in-50-45 mm of wheel tread, the maximum wear depth occurs in wheel flange, and the minimum wear depth occurs in wheel flange root. The wear velocities of wheel flange and rolling tread circle slow with the increase of running mileage. The vertical wear depth of wheel tread in simulation is less than test depth. The critical velocity of vehicle decreases when wheel is worn, the critical velocity of empty vehicle deceases by 13-18 kmºh-1, and the critical velocity of loaded vehicle deceases by 2-8 kmºh-1.
