Theory Study of Electro-Mechanical Coupling Vibration on Hybrid System Shafts

On the basis of characteristic parameters of motor and right-simplify,the model with hybrid system is established including flexible crankshaft and the rigid piston-connecting rod,rigid rotor,and then multi-dynamics analysis model of system is established.The dynamics characteristic of shaft system is completely studied when motor is in two different kinds of modes.Effect of electro-mechanical coupling on shafts system vibration is revealed completely,and contrasted with engine mode.Some beneficial conclusions are drawn.
