摘要

为了研究轴悬式驱动系统中电机质心位置对系统稳定性的影响，建立了两自由度单轮对驱动系统横向动力学的数学模型。分析表明：电机在前的单轮对驱动系统的横向稳定性要高于电机在后的单轮对驱动系统。最后根据该结论解释了2C0轴悬式机车前后转向架非对称蛇行现象产生的机理。

Abstract

To investigate the effects of the wheelset mass center of axle-mounted driving system on the hunting stability, a simplified model of single-wheelset driving system with two degrees of freedom was established. The result showed that the stability of drive system mass center in the front was better than that in the back, which explained the asymmetrical hunting phenomenon for 2C0 locomotives with axle-mounted driving system.
