High-Speed Contact Performance of Catenary-Pantograph System (2nd Report,Experimental Study on Effect of Parameters using a Scaled Model)

Abstract

The 1st report showed that contact loss and stress of a contact wire of the existing system were too large for the satisfactory current collection at a speed of 300km/h. In order to improve the situation,the effect of the parameters on the performance are studied using the same equipment. Tension and mass of contact wire and mass and upward force of the pantograph are changed. And a test is also done under the condition that the wave propagating velocity of contact wire is lower than the pantograph velocity. The experimental results as well as theoretical analyses indicate that contact loss and nondimensional stress of contact wire depend mainly on the wave propagating velocity of contact wire and the contribution of pantograph mass to the improvement is smaller than that of this velocity. © 1989, The Japan Society of Mechanical Engineers.
