摘　　要：建立了多刚体系统动力学模型,分析了抗蛇行减振器安装角度对铁道车辆系统动力学性能的影响。结果表明:抗蛇行减振器安装角度对车辆的非线性临界速度影响较大,水平安装时车辆具有最高的临界速度,随着安装角度的增大,临界速度不断降低,垂向平稳性指标不断增大;安装角度的变化对车辆曲线通过性能影响较小。The dynamics model for multi-rigidbody system is established.The effect of the installation angle of anti-hunting dampers on the dynamics performance of rolling stock is analyzed.The result shows that the installation angle of the anti-hunting damper has a fairly great effect on the non-linear critical speed of vehicles.The vehicle has the maximum critical speed when the damper is installed horizontally,with the increase of the installation angle,the critical speed reduces continuously,and the vertical ride comfort index increases continuously. The change of the installation angle has fairly small effect on the curve negotiation performance of vehicles.
