摘　　要：基于铁路大系统动力学理论建立了弓网动力学模型;并将机车顶部受电弓基座处的振动响应作为弓网系统的激扰应用于弓网动力学模型;探讨了车轨耦合振动对弓网接触压力的影响。Pantograph and OHL dynamic force model is established based on the railway great system dynamics theory; apply the vibration response at bracket of pantograph on top of locomotive roof in the pantograph dynamic model as the interference of the pantograph and OHL system; discusses the influence to the contact force between pantograph and OHL caused by vibration between locomotive and rail.
