针对中国提速铁路采用的 CH1 60 - 0简单链型悬挂接触网及 SS7受电弓 ,建立接触网的有限元模型 ,计算得出固有频率及相应的模态振型 ,导出其振动方程 ,并推导出受电弓非线性模型的运动微分方程 ,利用泰勒级数展开对非线性模型进行线性化 ,得到受电弓框架的等效参数 ,最后在这个基础上建立起受电弓 /接触网垂向耦合动力学模型。应用受电弓的线性模型及非线性模型 ,而且考虑机车、轨道激扰因素影响下 ,对接触网 /受电弓系统的动态进行了运行模拟计算并加以比较。

Dynamics model and behavior of pantograph/catenary system

For the civil CH160 0 simple stitched catenary on the high speed railway and SS7 pantograph,the finite element model of the catenary is sep up.The natural frequency and the corresponding mode are calculated and the equation of the vibration is educed.The nonlinear dynamical differential equation of the pantograph is list.By the Taylor series,the nonlinear model is linearized and the equivalent parameters of the frame of the pantograph are gained.The vertical coupling dynamic model of the pantograph/catenary system is established.Based on the linear model and the nonlinear model of the pantograph,the computation and the comparison of the simulation on the dynamic characteristic of the pantograph/catenary system are come out with the vibrating responses of the locomotive and track taken into consideration.
