摘要: 为了合理控制车辆轮对定位间隙, 提高磁流变耦合轮对车辆在高速时的横向动力学性能, 建立该车辆的空间动力学模型, 分析了轮对纵向定位间隙对车辆临界速度和曲线通过性能的影响。得出了纵向定位间隙的增大能使磁流变耦合轮对车辆的临界速度急剧下降, 轮对横移量和冲角、轮轨横向力和车体横移加速度快速增大; 只有在小间隙的条件下, 车辆在高速铁路上才具有较高的临界速度和较好的曲线通过性能。Abstract: In order to reasonably control the position clearance of vehicle wheelsets, improve the lateral dynamics performances of vehicle with magneto-rheological fluid (MRF) coupled wheelsets at high speed, a spatial dynamics model of vehicle was established, and the longitudinal position clearance influence of vehicle wheelsets on the critical velocity and curve passing performances of vehicle were analyzed.Analysis result shows that the clearance increase can make vehicle critical velocity descend sharply, make the lateral displacement and attack angle of wheelsets, the lateral force of wheel/rail and lateral acceleration of carbody largen rapidly; vehicle has higher critical velocity and better curve passing performances only in the condition of small clearance.
