Analysis of Active Vibration for HEVs through Electro-mechanical Coupling

In the present study an active vibration method of the electro-mechanical coupling system for the HEVs, is introduced. This work is part of a more wide research activity, dedicated to the development of hybrid electrical vehicles. This method is based on the electro-magnetic torque model of the permanent magnetic synchronous motor and the electro-mechanical coupling model. The method and its validation test took place alongside a consistent maintenance work that has allowed distinguish between different shaft. Then, the test results show that the method could reduce the torsional vibration of the electro-mechanical coupling system for the HEVs.
