摘　　要：利用多体动力学软件simpack建立了200 km/h速度等级机车的动力学模型,分析了机车通过平面曲线工况、纵断面工况和平纵断面组合工况时的安全性和平稳性,并根据现行铁道机车车辆动力学性能评定规范进行评价。结果表明:机车通过平面曲线工况时,在缓和曲线段内,其动力学性能变化较大;纵断面工况对机车垂向动力学性能的影响比对横向动力学性能的影响大;当考虑轨道不平顺时,平纵断面工况下机车的安全性与平稳性指标均属优良范围。Using multi-body dynamics software to set up a200 motives were analyzed by plane curve conditions, longitudinal combination conditions on safety and stability of locomotive. dynamics performance evaluation norms were evaluated. The km/h locomotive dynamic model, loco- vertical section and planar and vertical And under the existing railway vehicle results show that when locomotives get through the plane curve conditions, in the transition track, changes are large in the dynamic perform- ance locomotives. Influence of the vertical section on the locomotive vertical dynamics is larger than performance of the locomotive transverse dynamics. When considering the track irregularity, safety and stability of locomotive in the planar and vertical combination conditions are good indicators of the range.
