摘　　要：针对中国高速列车运行速度高、运营里程长、轮轨磨耗加剧,被动悬挂式抗蛇行减振器适应性较差,导致转向架抗蛇行稳定性能不足的情况,开展半主动悬挂抗蛇行减振器研究。首先,基于高速列车悬挂系统非线性和轮轨接触非线性特征,建立了高速列车模型、磁流变阻尼器模型、可变刚度和阻尼抗蛇行减振器模型;然后分析了抗蛇行刚度和阻尼参数对新轮轨和磨耗轮轨的车辆动力学性能的影响,并针对磨耗轮轨接触提出了半主动悬挂控制策略;最后,对比分析了被动悬挂和半主动悬挂车辆运行性能的差异。结果表明:通过采用半主动悬挂调整抗蛇行减振器的刚度和阻尼参数可大幅改善磨耗轮轨接触的车辆运行性能,保证构架不发生蛇行失稳,与采用被动悬挂抗蛇行减振器的车辆相比,车体横向加速度和构架横向加速度分别降低22.4%和16.0%。In view of the high speed,long operating mileage,and increased wheel-rail wear of high-speed trains,the passive suspension anti-yaw damper has poor adaptability,resulting in insufficient stability of the bogie anti-yaw performance.Therefore,a semi-active suspension anti-yaw damper is studied in this paper.Firstly,based on the nonlinear characteristics of high-speed train suspension system and the nonlinear characteristics of wheel-rail contact,a high-speed train model and a magneto-rheological damper model as well as a variable stiffness and damping anti-yaw damper model are established.Secondly,the influence of anti-yaw stiffness and damping parameters on the vehicle dynamics performance with new wheel-rail and worn wheel-rail is analyzed.The semi-active suspension control strategy is proposed for the worn wheel-rail contact.Finally,the difference of running performance between passive suspension and semi-active suspension vehicle is compared and analyzed.The results show that by using the semi-active suspension to adjust the stiffness and damping parameters of the anti-yaw shock absorb,the running performance of the vehicle in contact with worn wheel-rail can be greatly improved,which ensures that the frame does not suffer from yaw-instability.Compared with the vehicle with passive suspension,the lateral accelerations of the car body and the bogie are reduced by 22.4% and 16.0%,respectively.
