Through the workshop and loading vibration tests and analyses of a metro vehicle auxiliary converter,the floor vibration causes of metro car were determined,and the irrationality of onboard equipment vibration evaluation index was verified.A method was proposed to evaluate the influences of on-board equipment such as converters on the floor vibrations of metro car floors in the workshops or the laboratories.Test results show that the evaluation method errors are about 10% .The method may guide the selection of main vibration components such as transformers,fans,etc.,and avoid the emergence of large quantities of vibration faults.
