【Abstract】 In the design procedure of pantograph, virtual prototyping is applied to the study of the system of pantograph/ catenary in this paper. The three-dimensional simulative model involved in track, train, pantograph and catenary is set up. Based on the model, the coupling dynamic property of the system of pantograph/catenary, the vibrating responses in consideration of the track excitation and the dynamic stress of the simple catenary are analyzed. And consequently the role and advantage in design of high-speed pantograph brought from the application of virtual prototyping is made more definite.更多还原
