Abstract: An experiment instrument to simulate the wear behavior of light rail and subway current collector is designed.Based on the test data obtained on this instrument,a substitute copper alloy is selected which is better than the existing aluminum brass ZCuZn25Al6Fe3Mn3 in wear resistance.The experiment results indicate that the high manganese aluminum bronze ZCuMn12Al8Fe3Ni2 is an excellent material as light rail and subway current collector and with the graphite rod inserted into current collectors,the wear property of the current collector resistance will be improved further.
