非线性振动系统滞回模型研究综述

Literature review on hysteretic models for nonlinear vibration systems

许多振动机械系统或结构在动载荷作用下会表现出非线性滞回行为,在总结国内外研究成果的基础上,介绍了滞回模型的发展现状,并对非线性滞回系统的数学模型进行了分类阐述.但由于振动系统的多样性,建立一个具有一般性能的滞回非线性系统的数学模型是很困难的.

The nonlinear hysteretic properties occur in various vibration mechanical systems or structures under dynamic loading.Based on the foreign and domestic research work,the advances of hysteretic models are first highlighted in this study.Then,diverse mathematical models of nonlinear hysteretic systems are categorized and summarized.Thus for the diversity of vibration systems,it is finally concluded that a generic mathematical model has not been well addressed pertaining to nonlinear hysteretic systems.
