High frequency vibration characteristics of electric wheel

2017-7-21  The high frequency vibration of electric wheel system at 50–100 Hz has been attenuated and absorbed by the mechanical transmission parts and thus the horizontal vibration of vehicle body in the second order mode of QV-EWS at 4 Hz is the most remarkable. This surge phenomenon is a common problem for in-wheel motor driven vehicle at low speed.
