摘要
本文提出了一个三次多项式的迟滞模型,并用Wiener-Hermite函数级数展开的方法求解,得到了不同阻尼及不同的非线性强度时系统响应的均方值σ(t)。不仅从理论上而且通过实验证实了用这种方法求解迟滞系统的响应是行之有效的、简便的。
In this paper a tripolynomial hysteretic model is proposed. Using the Wiener-Her-mite Series expansion method,we obtained the mean square response of the hysteretic system under white-noise excitation in the case of various values of nonlinear strength and damping coefficient. A proof test is given and the agreement of the experimental results with the calculating results shows that the method suggested in this paper is feasible and simple.
