This paper overviews systematically the recent research results concerning coupled mechanical and electrical vibration of rotor system and coupled magnetical and solid vibration of the stator system of generator set.These results can be divided into three fields:nonlinear vibration excited by electrical and magnetical forces; nonlinear dynamics of coupled mechanical and electrical system; couled magnetical and solid nonlinear vibration of the stator of the generator set. Five subjects are introduced in detail.They are: parametrically excited resonance by coupled electrical and magnetical parameters; multiple resonance excited by coupled electrical and magnetical parameters; multiple resonance excited by couled electrical and magnetical forces; nonlinear vibration of coupled mechanical and electrical system of AC motor; dynamic bifurcation, dynamic instability and vibration of coupled mechanical and electrical system;multiple resonance of coupled magnetical and solid stator system.63 relative papers are numerated and reviewed,in most of which, theoretical results are testified by experiments.Finally, prospects of the practical use of these research results and the further development of investigation in this field are discussed.
