Bouc-Wen 磁滞模型是工程领域最广泛接受的平滑变化微分模型之一。对于Bouc-Wen模型的不同参数，振动系统的软化或硬化响应是非线性的。通过数值模拟研究了具有不同Bouc-Wen模型参数的单自由度振子的频率响应、分岔和混沌。研究了滞回参数对振动系统非线性动态响应的影响，发现了一些新现象。 (c) 2006 Elsevier Ltd. 保留所有权利。
Bouc-Wen hysteresis model is one of the most widely accepted smoothly varying differential models in the engineering field. With different parameters of Bouc-Wen model, the vibrating system is nonlinear for its softening or hardening responses. Frequency responses, bifurcation and chaos of a SDOF oscillator with different parameters of Bouc-Wen model are investigated by means of numerical simulation. The influence of hysteretic parameters on nonlinear dynamic responses of vibrating system is studied, some new phenomena are detected. (c) 2006 Elsevier Ltd. All rights reserved.
