【Abstract】 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.更多还原
