摘　　要：为了探究地铁列车通过曲线时主动径向转向架对轮轨磨耗的影响,基于Simpack和Matlab/Simulink软件搭建主动径向车体动力学模型,通过轮轨横向力、轮对冲角、轮对横向位移以及脱轨系数等动力学仿真指标来评价车辆的曲线通过性及安全性,最后利用JENDEL磨耗模型来评价车辆过曲线时轮轨的磨耗性能。研究结果表明:编制控制算法时,利用侧滚角速度对滤波后的横向加速度信号进行实时补偿是合理的,补偿后作动器实际动作位移与理论动作位移相比只存在少许波动。当车辆通过曲线时,主动径向转向架与常规转向架相比,轮对冲角最大值由4.5 mrad下降到1.2 mrad,降低了73.3%;轮轨横向力最大值由14.1 kN降至1.8 kN,下降了87.2%;轮轨之间的横向位移也从12.2 mm下降到8.5 mm,下降了30.3%;脱轨系数从0.225下降到0.05,降低了77.8%,车辆的曲线通过性和运行安全性得到了提高。主动径向转向架使轮轨的磨耗位置发生改变,从轮缘和钢轨侧面磨耗发展到了车轮踏面和钢轨头顶面磨耗,减缓了轮缘和钢轨侧面的磨损,延长了车轮镟修周期,增加了使用寿命。利用JENDEL磨耗模型进行仿真分析,主动径向转向架与常规转向架相比,轮轨磨耗量明显降低,主动轮对外侧车轮和轨道磨耗量分别降低74.5%和75.9%,内侧车轮和轨道分别降低61.6%和61%,从动轮对外侧车轮和轨道磨耗量分别降低39.2%和43.7%,内侧车轮和轨道分别降低41.5%和44.3%。研究成果为主动径向控制的有效性提供了依据。To explore the impact of active radial bogies on wheel rail wear when subway trains pass through curves,an active radial vehicle body dynamics model was built based on Simpack and Matlab/Simulink.Dynamic simulation indicators such as wheel rail lateral force,wheel offset angle,wheel set lateral displacement,and derailment coefficient were used to evaluate the vehicle’s curve passing performance and safety.Finally,the JENDEL wear model was used to evaluate the wheel rail wear performance when the vehicle passes through curves.The research results are drawn as follows.It is reasonable to use roll angle velocity to compensate the filtered signal in real-time when developing control algorithms.After compensation,there is only a slight fluctuation between the actual action displacement of the actuator and the theoretical action displacement.When the vehicle passes through the curve,compared with conventional bogies,the active radial bogie has a 73.3% decrease in the maximum wheel offset angle from 4.5 mrad to 1.2 mrad,a 87.2% decrease in the maximum lateral force between the wheel and rail from 14.1 kN to 1.8 kN and a 87.2% decrease in the lateral displacement between the wheel and rail from 12.2 mm to 8.5 mm.The derailment coefficient fluctuates also around zero.The vehicle’s curve passing ability and operational safety are improved.The active radial bogie changes the wear position of the wheel and rail,from the wear on the wheel flange and rail side to the wear on the wheel tread and steel rail head top surface,slowing down the wear on the wheel flange and rail side,prolonging the wheel turning cycle,and increasing the service life.Using the JENDEL wear model for simulation analysis,it is found that compared with conventional bogies,active radial bogies have significantly reduced wheel rail wear.The wear of the outer wheel and track of the active wheelset decreases by 74.5% and 75.9%,while the wear of the inner wheel and track decreases by 61.6% and 61%.The wear of the outer wheel and track of the driven wheel d
