中文摘要：

建立摆式列车多刚体系统动力学模型、受电弓非线性动力学模型和接触网有限元动力学模型。将受电弓基座通过滚轮安装在车顶的导轨上,使用伺服电动机驱动受电弓框架在导轨上横向运动,实现受电弓横向主动控制。当列车在直线轨道上运行时,利用受电弓的横向主动控制,根据导轨形状约束使受电弓框架同时垂向移动,从而减小弓网接触压力波动。在曲线轨道上,受电弓需要相对车体反向倾摆,使弓网接触点在弓头上的横向位置满足受电弓工作范围要求。并且使受电弓框架垂向位移和侧滚角度足够小,弓网接触压力达到车辆正常曲线通过时的水平。设计两种受电弓导轨外形。采用数值仿真方法,比较分析两种导轨下的控制效果和弓网振动。计算结果表明,直线轨道上和曲线轨道上的受电弓横向主动控制效果明显,能有效提高弓网接触压力最小值,减少离线发生次数,同时不会改变弓网接触压力的平均值。

英文摘要：

The rigid multibody dynamic model of the tilting train,the nonlinear dynamic model of the pantograph and the FEM model of the catenary are set up.The pantograph base is connected with the carbody roof through a guide way and rollers.The lateral active control of the pantograph is realized by applying the servo-motor to control the motion of the pantograph base along the guide way.When the train runs on straight tracks,the vertical motion of the pantograph frame is adjusted by controlling the pantograph lateral motion on the guide way,in order to reduce the fluctuation of the pantograph-catenary contact force.When operating on curved tracks,the pantograph should tilt in the opposite direction of the carbody to make the lateral position of the pantograph-catenary contact point in the working range of the pantograph head.In the mean time,the vertical and roll motions of the pantograph fame should be as small as possible,so that to make the contact force as normal as the conventional train.Two shapes of guide way are designed.Numerical simulation is adopted to analyze the control performance and the pantograph-catenary vibration.It can be seen from the results that the effect of the lateral active control is evident whether on the straight tracks or on the curved tracks.The minimum value of the contact force is increased efficiently,the number of pantograph and catenary separations is reduced,and at the same time the mean value of the contact force is not changed.
