受其可控和场相关刚度/阻尼特性的启发，已经增加了磁流变弹性体（MRE）的研究和开发，用于使用MRE隔离器或吸收器来减轻不希望的结构或机械振动。最近，一个突破性的试点研究的高度创新的原型自适应MRE基础隔震器的发展，具有实时自适应控制的基础隔震结构对各种类型的地震，包括近或远断层地震的能力，已由作者报道。作为进一步努力，以改善建议的MRE自适应基础隔离器，并解决一些缺点和挑战，本文提出了系统的研究，发展一种新的高度可调MRE基础隔离器，包括实验测试和表征的新的隔离器。一种软MR弹性体已被设计，制造和纳入新的MRE基础隔离器，其目的是在中等水平的磁场下获得高度可调的剪切模量的层压结构。对这种新型自适应MRE基础隔振器进行了全面的静态和动态试验，以检查其特性并评估其性能。实验结果表明，这种新型磁流变弹性基础隔振器在中等磁场作用下，可以显著地改变隔振器的横向刚度，最大可达1630%。这种高度可调的MRE基础隔震器使得真正实时自适应（例如半主动或智能被动）隔震系统的设计和实施变得可行。
Inspired by its controllable and field-dependent stiffness/damping properties, there has been increasing research and development of magnetorheological elastomer (MRE) for mitigation of unwanted structural or machinery vibrations using MRE isolators or absorbers. Recently, a breakthrough pilot research on the development of a highly innovative prototype adaptive MRE base isolator, with the ability for real-time adaptive control of base isolated structures against various types of earthquakes including near-or far-fault earthquakes, has been reported by the authors. As a further effort to improve the proposed MRE adaptive base isolator and to address some of the shortcomings and challenges, this paper presents systematic investigations on the development of a new highly adjustable MRE base isolator, including experimental testing and characterization of the new isolator. A soft MR elastomer has been designed, fabricated and incorporated in the laminated structure of the new MRE base isolator, which aims to obtain a highly adjustable shear modulus under a medium level of magnetic field. Comprehensive static and dynamic testing was conducted on this new adaptive MRE base isolator to examine its characteristics and evaluate its performance. The experimental results show that this new MRE base isolator can remarkably change the lateral stiffness of the isolator up to 1630% under a medium level of magnetic field. Such highly adjustable MRE base isolator makes the design and implementation of truly real-time adaptive (eg semi-active or smart passive) seismic isolation systems become feasible.
