本文根据单自由度振动系统对高斯白噪声激励的响应的统计特性,在Fokker-Planck方程的基础上,推导出一种非参数识别方法。并通过算例考查了方法的效果。
In this paper, based on the Fokker-Planck equation, a non-parametric identification method is derived based on the statistical properties of single-degree-of-freedom vibration system response to Gaussian white noise excitation. Through an example to test the effectiveness of the method.
