Experimental Study on Service Performance of Pantograph of Railway Electric Locomotive With 30-ton Axle Load
The stability of pantograph transmission system of railway electric locomotive with axle load of 30 tons will directly affect the fluctuation range of pantograph catenary dynamic contact force,thus affecting the performance of pantograph catenary matching.The service performance test of pantograph of railway electric locomotive with axle load of 30 tons is designed,and the static lifting force of pantograph of electric locomotive operating at different speed levels is tracked and measured.The difference of measurement results under different service mileage and different speed operating conditions is studied by using one-dimensional variance analysis method.Finally,the development trend of measurement results is analyzed.
