| 摘 要： | 为了改善我国重载牵引电力机车的轮缘磨耗现象,本文采用多刚体动力学软件SIMPACK分别建立了采用径向转向架和传统转向架的C_0-C_0轴式HX_D1C型电力机车动力学模型,通过比较两者的非线性稳定性、直线运行性能和曲线通过性能,结果说明采用径向转向架的HX_D1C型电力机车可以满足120 km/h速度的运用要求;直线运行性能优良;除了通过曲线时车体横向和垂向加速度外,曲线通过性能优于原车;降低轮缘磨耗显著,在100km/h以下减磨效果明显,各计算工况下轮缘磨耗降低60%以上,车轮磨耗功降低47%以上。

| Abstract: | Models of type HXD IC electric locomotive of six axles （i. e. 2C0） is established by SIMPACK to improve the wheel flange wear for heavy hauling locomotive. Comparisons are made with regard to the stability and running performances on tangent or curved tracks of the locomotive with conventional and radial bogies. It is showed that the locomotive of 2C0 axles with radial bogies can meet the running need at 120 km/h. The riding quality index of it is good. The curving performances are superior to the locomotive with conventional bogies except lateral and vertical accelerations. The wheel flange wear is remarkably reduced, especially under the speed of 100 km/h. The wheel flange wear decreases by above 60% and the wheel wear work decreases by above 47% under every calculated condition. |
