non-stationary random vibration - 1
This article established the covariance matrix method of non-stationary random vibration. 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。 - 2
A new method for a vertical non-stationary random vibration analysis of vehicle-bridge systems subjected to track irregularity excitations is proposed. 提出了考虑轨道高低不平顺时进行车桥耦合系统垂向非平稳随机振动分析的新方法。 - 3
The results may better reflect the non-stationarity of ground motion in time domain and are closer to reality than those by wave theory and stationary random vibration theory. 由于这种方法能较好地反映地面运动的时域非平稳性，所以得到的计算结果更真实。
