高速电力机车二系弹簧系统的改进设计

Optimum design of two spring system of high speed electric locomotive

高速电力机车行驶速度很高 ,轮缘冲击内轨道的激振力显著增强 ,引起一系和二系弹簧系统的刚度降低 ,蛇形运动加剧和晃车现象产生。为此 ,本文对两系弹簧系统的设计进行改进。计算表明 :改进后的两系弹簧系统在各个方向的刚度都显著增加。

The high speed electric locomotive run so fast that the shock force of wheel rim collision orbit increased shamply. That result in the two spring system stiffness decreasing. Moving like snake and sway of locomotive occur. So the paper present the new design for two spring system. Computation express that the stiffness indirection in new two spring system have increased.
