摘要：为使地铁车辆在保证直线稳定性的同时，又能改善曲线通过性能，本文阐述了主动径向转向架的导向机理，并基于多体动力学建立了主动径向转向架联合仿真模型，从理论角度研究了基于冲角的径向线控制策略和基于纵向蠕滑力的纯滚线控制策略，从工程实用角度研究了基于二系回转角和线路信标的相对摇头角控制策略，对比论证了工程控制策略的可行性。研究结果表明：与传统转向架相比，主动径向转向架能够在车辆通过曲线时，控制轮对趋于径向线位置，大幅提高曲线通过性能；采用不同控制策略均可以显著减小轮对冲角，改善轮轨磨耗。

Abstract：This paper explores the control strategy of metro vehicle active radial bogie in order to ensure the linear stability and improve the curve passing performance of metro vehicles. The guiding mechanism of active radial bogie was described and the co-simulation model of active radial bogie was established based on multi- body dynamics. The radial line control strategy based on wheelset attack angle and the pure roll line control strategy based on longitudinal creep force were discussed. The control strategies of relative yaw angle based on the yaw angle of secondary suspension and line beacon were studied from the perspective of engineering application. Engineering control strategies were compared and the feasibility was demonstrated. The results show that compared with the traditional bogie, the active radial bogie can control the wheel set to the radial line position when the vehicle passes through the curve, and greatly improve the curve passing performance. Different control strategies can significantly reduce both the wheel offset angle and the wheel rail wear.
Key words：metro vehicle；active radial bogie；control strategy
