| 摘 要： | 受电弓与接触网之间的振动问题,一直是制约电力机车提速的关键之一。本文对2种类型接触网的刚度进行了非线性最小二乘曲线拟合,并给出了统一的拟合公式,建立了3自由度弓网系统模型,采用最优控制策略,对不同运行速度下弓网间接触力进行主动控制。仿真结果表明,采用主动控制受电弓可以有效地抑制接触力的波动,控制效果较好。

| Abstract: | One of the main problems limiting train speed raising is the contact oscillation between the pantograph and the catenary. Stiffness of two kinds of curves is fitted by using the non-linear least square method and a unified fitting formula is presented in this paper. A 3-D model of the pantograph-catenary is established. The optimal control strategy is adopted to actively control the contact forces between the pantograph and catenary under the conditions of different train velocities. Simulations show that this active control method can reduce fluctuations of the contact forces and the control effect is fairly good. |
