【Abstract】 For the purpose of revealing the influence of colored noise on the response of oleo damper subject to special random excitation, this paper deals with the one dimension problem caused by colored noise by using the two dimensions Markov equation. The probability density function of velocity response of oleo damper excited by exponential colored Gaussian noise has been obtained. In addition, a special expression of probability density function of velocity response under the condition that the outer excitement correlation time of exponential colored Gaussian noise is long enough has been got. These results have been verified by numerical simulation.更多还原
