摘要
针对D19E型内燃机车车轮磨耗问题,分析了越南铁路基本技术及D19E型内燃机车结构,采用SIMPACK软件建立了D19E型内燃机车动力学模型,并根据越南干线实际情况建立了线路模型。提出了基于机车动力学模型、FASTSIM算法与Braghin踏面磨耗模型为一体的车轮磨耗计算模型,并发展了相应的数值方法。利用该模型对D19E型内燃机车车轮磨耗进行了仿真分析,采用小波滤波平滑方法对踏面磨耗深度数据进行了平滑,并与现场实测结果进行了对比。研究结果表明,磨耗主要发生在踏面上(-50 mm^45 mm)范围内,轮缘根部处磨耗最大;踏面磨耗量的仿真结果与现场实测结果基本一致,说明该仿真模型能较好地模拟机车车轮磨耗的演化过程,可靠性高。
Aiming at the wheel wear problem of D19E diesel locomotive, the basic technology of Vietnam railway and D19E diesel structure were analyzed, the D19E diesel locomotive dynamics model was built by SIMPACK software and a railway line model was built based on Viet- nam railway line. A model in which locomotive dynamics, FASTSIM algorithm and Braghin profile wear model were combined, was devel- oped to pridict the wheel tread wear. The wheel wear of D19E diesel locomotive was simulated based on this model, the tread wear depth data was smoothed based on sliding mean method, and the simulation results were compared with that of field measured results. The results indi- cate that, the wear occurs in （ -50 mm -45 mm） of wheel tread, the maximum wear depth occurs in wheel flange root. The wear depth of wheel tread in simulation results and field measured results are similar, show that presented simulation model is feasible to predict the wheel tread wear of locomotive, high reliability.
