An adjustable mechano-electric-damper was developed and its performance was studied through the dynamic loading tests. The mechanical model of this variable damper was derived to construct the control system of the developed variable damper. The derived relation between the damping force and the induction current was implemented into a micro-computer composed of the high speed digital signal processor which is the main part of the control system. The developed control system of the variable damper worked well to demonstrate wide capability for generating arbitrary hysteresis loops. A hybrid experiment was also performed to demonstrate the efficiency of developed variable damper by using recently assembled hybrid simulation system which composed of the seismic motion generator unit, the structural response analysis unit and the control signal generator unit for variable damper. The effectiveness of not only the developed variable damper but also the already developed hydraulic variable damper is confirmed through several real-time hybrid experiments for a base isolated 2 degree-of-freedom structural model.

研制了一种可调式机电阻尼器，并通过动载试验研究了其性能。推导了该可变阻尼器的力学模型，构建了所研制的可变阻尼器的控制系统。推导出的阻尼力与感应电流之间的关系式被实现到由高速数字信号处理器组成的微型计算机中，该微型计算机是控制系统的主要部分。所开发的可变阻尼器的控制系统工作良好，表现出广泛的能力，产生任意的磁滞回线。最后，利用由地震动发生器单元、结构反应分析单元和可变阻尼器控制信号发生器单元组成的混合仿真系统，进行了混合试验，验证了可变阻尼器的有效性。不仅开发的可变阻尼器，但也已经开发的液压可变阻尼器的有效性，通过几个实时的混合动力基础隔离的2自由度结构模型的实验证实。
