| 摘 要： | 为了改善提速机车高速运行时的横向动力学性能,通过分析我国主型2C0提速架悬机车的牵引电机悬挂方案,对分别采用刚性架悬和弹性架悬方案时机车的横向稳定性、平稳性、轮轴横向力、轮重动态变化等进行了比较研究.结果表明,采用弹性架悬方案时,机车各项直线高速运行指标均有所改善,且机车的动力学性能对悬挂参数的敏感性减弱,因而有利于机车在长期运行中保持稳定的动力学性能.

| Abstract: | To improve the lateral dynamic performance of a speed-raising locomotive running at a high speed, the lateral stability, ride index, lateral wheelset force and change in wheel load for a traction motor respectively elastically and rigidly mounted on the frame were compared and investigated based on analyzing the traction motor suspension designs of 2C0 speed-raising locomotives. The result shows that when a motor is elastically mounted on the frame, all performances of a locomotive running at a high speed on a straight track are improved in some degree, and its dynamic performances become less sensitive to suspension parameters so as to keep the stable dynamic performance of a locomotive in long-time running. |
