| 摘 要： | 车下大质量单元的悬挂方式对车辆的动力学性能有着很大的影响,本文从轮轨间横向动作用力、驱动装置工作环境以及车辆曲线通过性能等几个方面分析了驱动装置横向弹性悬挂对于车辆动力学的影响,研究结果显示,驱动装置弹性横向悬挂可以显著降低轮轨间横向作用力,同样显著降低了驱动装置横向加速度,由此改善了驱动装置的工作状态。

| Abstract: | The suspension of heavy unit under the floor drastically affects the dynamic performance of a railcar.This paper analyzes the influence of transverse elastic suspension in a drive unit on the vehicle dynamics.Research and testing results indicate that the elastic suspension can dramatically reduce both the transverse force between rail and wheel and the transverse acceleration of the drive unit,consequently improving the operating conditions of the drive unit. |

| Keywords: | railcar drive unit transverse elastic coupling dynamic performance |
