摘要
针对某200 km/h速度等级B_0-B_0客运机车跨线运行安全性,采用多体系统动力学软件SIMPACK建立了该机车动力学模型,在不同轮缘厚度标准踏面的使用及客运专线轨距和轮对内侧距公差极限条件下,选取4种轮轨间隙极限工况进行动力学仿真分析。结果表明:在轮轨间隙极限工况下,该机车的横向稳定性,直线和曲线通过性能均可以满足安全运行的要求;随着轮轨间隙的增大,该机车的动力学性能尤其是横向性能下降。
Aiming at the security of the certain 200 km/h speed level B_0-B_0 passenger locomotive transport across the line,dynamic model of the locomotive was established with multi-rigid-body dynamics software SIMPACK.Under the conditions of using different thicknesses rim standard tread,and the tolerance limit of dedicated passenger railway track and back-to-back distance of the wheelset,four working conditions of the wheel/rail limit gap were completed dynamics analyses.The results showed that the horizontal stability,straight and curve negotiation of the locomotive could meet the requirements of safe operation under the working conditions of the wheel/rail limit gap;with the increase of wheel/rail clearance,the locomotive dynamics performance became worse,especially for horizontal performance.
