摘要针对O型钢丝绳隔振器具有非线性弹性刚度、非对称迟滞动态特性,采用改进的归一化Bouc-Wen模型并基于该模型对钢丝绳隔振器动态特性参数识别方法进行研究。提出新的简单有效的两阶段识别方法进行参数辨识研究。通过数值仿真与周期性加载试验相结合方法对所提方法进行验证。结果表明，参数识别方法可准确有效识别出O型钢丝绳隔振器模型参数，且试验迟滞曲线与识别模型迟滞曲线吻合较好。

Abstract：In the present study, a modified normalized Bouc-Wen model is adopted to describe the hysteretic behaviour of an O-type wire-cable vibration isolator which exhibits nonlinear elastic stiffness and asymmetric hysteresis dynamic behavior. This paper deals with the parametric identification of O-type wire-cable vibration isolator based on modified normalized Bouc-Wen model. A new simple yet effective two-stage identification method is developed for identifying the model parameters. Numerical simulations and periodic loading experiments were carried out to validate the proposed identification method. The results verify that the proposed identification method is effective and accurate for identifying the model parameters of O-type wire-cable vibration isolator, and the experimental hysteresis loops are close to the identified hysteresis loops.

Key words： O-type wire-cable vibration isolator hysteresis simulation identification method modified normalized Bouc-Wen model
