摘要
本文讨论动力系统在相关多激发作用下的随机振动离散分析方法。为了直接在实际计算中使用该方法,本文对均值与均方响应的递推格式进行了实用化处理。然后,本文给出了利用该方法对一个双自由度体系进行计算的结果。由计算结果可以看出,该方法对动力系统在时间相关荷载激发下的随机振动分析是十分有效的。
A discrete analysis .method for random vibration of structures under the excitations correlated in time domain is discussed in this paper. The practical form of the recurrence formulations for the mean and mean square responses of structures arc obtained. Then the calculation results of a two-degree-of-freedom System are given by using this method. These results illustrates the effectiveness of the method to the problems related with excitations correlated in time domain,
