ABSTRACT
ABSTRACT: TheV500 high-speed pantograph is the new developed products funded by National Science and Technology Support Project of China. Its key performance, such as aerodynamic characteristics and dynamic interaction between pantograph and catenary system, is taken into consideration. Especially for aerodynamic characteristics it is very complex and difficult for the numerical simulation to calculate the accurate results through CFD software. Thus the data is acquired through the experiment in wind tunnel. Besides the general measurement of the lift force and the whole drag force, the acceleration, the surface pressure and strain, are also the important parameters from the speed of 400 to 600 km/h. Regardless of the open or close direction of the pantograph, both of the drag force and the lift force become bigger with the increase of the speed. For the lift force, it is different from the value in EN50367 and the deviation is from −7.68% to 7.57%, and at the speed of 500 km/h the difference reaches the minimum 8.7N.The whole drag force is lower than the existent high-speed pantograph at the same condition. The maximum different value is 39 N at the speed 550 km/h. Base on this, the mathematical model of pantograph/catenary system is established with the existent high-speed elastic stitched catenary system.
