本文报道了一种实验装置,旨在评估新设计的磁流变弹性体(MRE)隔震器的性能。为了进一步探索 MRE 隔离器的场相关刚度/阻尼特性,进行了一系列实验测试。基于对实验响应和 MRE 隔离器特性的分析,提出了一种能够重现独特的 MRE 隔离器动力学行为的新模型。验证结果验证了模型描绘 MRE 隔离器的有效性。然后提供了对场相关参数的研究,以使模型在波动磁场下有效。为了充分探索所提出模型的机制,对所提出模型对每个参数的依赖性进行了研究。
This paper reports an experimental setup aiming at evaluating the performance of a newly designed magnetorheological elastomer (MRE) seismic isolator. As a further effort to explore the field-dependent stiffness/damping properties of the MRE isolator, a series of experimental testing were conducted. Based upon the analysis of the experimental responses and the characteristics of the MRE isolator, a new model that is capable of reproducing the unique MRE isolator dynamics behaviors is proposed. The validation results verify the model’s effectiveness to portray the MRE isolator. A study on the field-dependent parameters is then provided to make the model valid with fluctuating magnetic fields. To fully explore the mechanism of the proposed model, an investigation relating the dependence of the proposed model on every parameter is carried out.
