In this paper, an improved Gaussian technique is presented for solving the problems of the non-linear random vibration fo multi-degrees of freedom. 本文提出了一种求解多自由度非线性随机振动问题的改进的高斯闭合法。
Non-Gaussian moment method for random vibration of nonlinear systems 非线性振动中的非高斯矩方法
In addition, bispectrum can suppress the Gaussian random components and the symmetric non-Gaussian random components of vibration signals, meanwhile retain the information of asymmetric non-Gaussian random components. 另外,双谱能抑制掉振动信号中的高斯随机成分、对称非高斯随机成分,保留非对称非高斯随机成分信息,这有利于降低噪声、非故障随机振动的干扰。
