【摘要】 建立了摆式车辆系统动力学模型,采用数值仿真方法研究了摆式列车曲线通过时径向转向架的动力学性能。仿真结果表明,摆式列车以高于常规列车30%的速度通过曲线时,采用迫导向径向转向架能有效降低轮轨磨耗和改善动力学性能,主动控制径向转向架能达到与迫导向径向转向架相近的效果,两者的曲线通过性能均比无导向和自导向径向转向架好,且具有较高的非线性临界速度。可控径向转向架能方便地调整径向增益,且在作动器卸荷后具有与自导向径向转向架一样的性能。更多还原

【Abstract】 The dynamics model of a tilting car system is established.The numerical simulation method is used to study the dynamics performance of radial bogies when the tilting train negotiates a curve.The simulation results show that,when a tilting train negotiates a curve at a speed 30% higher than a normal train,the application of forced steering bogies can effectively reduce the wheel-rail wear and improve the dynamics performance,the actively controlled radial bogie can have the similar effect as the forced steering radial bogie,the curve negotiation performances of both bogies above are better than those of the non-steering and the self-steering bogies,and they have fairly high non-linear critical speed.The controlled radial bogie can conveniently ajust the radial gain,and has the same performance as the self-steering radial bogie when the actuator is unloaded.更多还原
