Summary:

Gear vibration and noise evaluation approaches are commonly proposed with a variety of way in a transmission system while complicated and obscured, it is difficult to provide a feasible basis for the gear development of E-drive system. Based on the vibration mechanism of E-drive gear meshing and order tracking theory on rotating machinery, this paper expressed the details of gear vibration evaluation approach accordingly during E-drive system's development phase, combined with objective testing and subjective evaluation correlation analysis, raised the meshing gear order vibration evaluation approach by the means of the testing data target curve-fitting, also verify the reasonableness and validity of this approach on a HEV matched with E-drive system by means of subjective evaluation and objective measurement before and after the gears' optimization, the clarification shows that significant correlation between subjective evaluation and objective measurement of the meshing gears both of the 23rd and 46th order, It's been further proved that this approach is reasonable, effective and feasible for the vibration measurement and evaluation of the meshing gears of the E-Motor transmission system. Meanwhile, it also can be used as a reference for the development and diagnosis of powertrain and vehicle
