EXTENDED AVERAGED EQUATION METHOD AND APPLICATION ON ANALYZING SOME NONLINEAR DETERMINISTIC VIBRATIONS

The paper presents an extended averaged equation approach to the investigation of nonlinear vibration problems. The proposed method is applied to some free/self excited oscillator, nonlinear free and forced oscillations of a suspension system with two-degree-of-freedom. The results in analyzing the vibration systems with different nonlinearity show the efficiency and advantages of the method.
