| Abstract: | An impact attenuation vibration system excited by Gaussian white noise was studied in this paper,a new mechanical model was presented.Starting from stochastic differential equation and with unstant random achieving rale,the 2nd order partial differental equation satisfied by two dimentional joint probability density of the primary oscilation displacement and velocity response was obtained, and the precise solution of the probability density function is found. |
