| 摘 要： | 本文提出求解非平稳随机振动问题的一种新方法——协方差矩阵法。本法用于多自由度振动系统进行检验,证明解非平稳随机振动问题是可靠和有效的。既可用于线性时不变系统,又可用于线性时变系统。只要能得到激励的均值或协方差矩阵,便可采用本法求得系统响应的均值和协方差。

| Abstract: | This article established the covariance matrix method of non-stationary random vibration. Using this method, a multiple degree of freedom vibration system is calculated. In comparison with the theoretical solution, it is shown that this method is convenient and effect to study non-stationary vibration problems. |
