| Abstract: | By useing the vibratory response at the substrate of pantograph on the roof of locomotive as the disturbance of catenary-pantograph system and put it into catenary-pantograph dynamics model, we established the catenary-pantograph dynamics model based on the dynamics theory of railway system, then analyzed the effect of parameters such as the speed, catenary and pantograph on the catenary-pantograph contact force by using MATLAB software. |
