NEW CRITERION FOR GAUSSIAN EQUIVALENT LINEARIZATION

Within the scope of Gaussian equivalent linearization, a new probabili stic criterion for determining the coefficients of the linearized equi valent equation is proposed to treat stationary responses of dan-linea r systems under zero mean Gaussian random excitation. Applications to the Duffing and Van der Pol oscillators subjected to white noise are p resented that show significant improvement over corresponding accuracy of the classical Gaussian equivalent linearization for hath weak and strong non-linearity.
