DISCRETE ANALYSIS METHOD OF RANDOM VIBRATION
随机振动离散分析方法

Discrete Analysis Method of Random Vibration is proposed in this paper. Anew recurrence formula which can be used to calculate the stationary and non-stationary mean and mean square responses is given, and its unconditional stability is proved. By using of this formula, the accurate mean and mean square responses of a linear or an equivalent linearized nonlinear vibration problem can be obtained.
