摘要

为了进一步提高现有中速地铁车辆的稳定性，解决由于结构剩余空间不足导致无法加装抗蛇行减振器的问题，提出一种适用于铁道车辆的旋转式抗蛇行减振器（下称旋转减振器），该减振器不仅安装空间小、安装灵活，还具有结构可靠、散热性能更好的优势。基于旋转减振器的工作原理，建立了旋转减振器的数学模型以及更为准确的AMESim模型，并通过MATLAB/Simulink建立旋转减振器AMESim模型与地铁车辆动力学SIMPACK模型的联合仿真，对旋转减振器的阻尼特性参数进行优化匹配（包括卸荷力及卸荷力矩），分析旋转减振器对车辆系统动力学性能的影响。仿真结果表明：旋转减振器能够代替抗蛇行减振器提供回转阻尼，在保证曲线通过安全性的条件下，使中速地铁车辆具有更好的稳定性和平稳性。

Abstract

In order to further improve the stability of existing medium speed metro vehicles and solve the problem that yaw dampers cannot be installed due to insufficient structural space

a rotary yaw damper (hereinafter referred to as rotary damper) suitable for railway vehicles is proposed

which not only has small installation space and flexible installation

but also has the advantages of reliable structure and better heat dissipation performance. Based on the working principle of the rotary damper

the mathematical model of the rotary damper and the more accurate AMESim model are established

and the co-simulation of the AMESim model of the rotary damper and the subway vehicle dynamics SIMPACK model are established through MATLAB/Simulink to optimize and match the damping characteristic parameters of the rotary damper (including unloading force and unloading torque)

and analyze the influence of the rotary damper on the dynamic performance of the vehicle system. The simulation results show that the rotary damper can replace yaw damper to provide the rotary damping

and make the medium speed metro vehicle have better stability and stationarity under the condition of ensuring the safety of curve passing.
