滞回非线性模型研究现状

Research Status of Hysteretic Nonlinear Mode

在实际工程中,具有滞回非线性特性的材料有很多种,经过对国内外滞回非线性模型研究进行分析和总结,将其分为分段直线滞回模型(干摩擦理想模型、双线性模型、C aughy双线性模型、N eilsen退化双线型模型、C lough退化双线型模型)和曲线滞回模型(D avidenkov模型、B ouc-W en模型、迹法模型)两大类,论述了各种模型的研究对象、适用条件及非线性方程,为滞回模型的选择提供参考依据。

In actual project, there are many kinds of hysterctic nonlinear materials. After analyzing and summarizing the study of hysteretic nonlinear models from domestic and overseas, it can be divided into two parts： pieeewise linear hyslerelic model （dry friction model, bilinear model, Caughy bilinear hysteretie model, Neilsen degradation bilinear model, Clough degradation bilinear hysteretie model） and curve hysteretic model （Davidenkov model, Bouc-Wen model, trace method model）. This paper discusses the research objects, application conditions and nonlinear equations of these models,which can provide reference to choose hysteretic nonlinear models.
