| Abstract: | The principle of the noise reduction and the structure of damped wheels for the city rail transit vehicles are presented.The comparison test for noise reduction of damped wheels and ordinary wheels has been carried out when vehicles entering in and out of a straight or curved track section and running at low-speed or high-speed.Analysis of the test results are carried on from sound pressure,level frequency spectrum and time spectrum,which verify the practical effect on noise reduction of the damped wheels. |
