从能量的角度研究对隔震换能控制系统对建筑结构的减震控制作用,它既能通过转换地震能量来减轻结构的振动,又可以利用转换来的能量作进一步的振动控制。通过研究换能装置的控制力与隔震层刚度比的关系,提出了换能装置控制力的建议公式,并研究了不同换能装置与隔震层设计组合对换能效率和控制效果的影响,给出了隔震换能系统的设计流程,可使隔震换能系统换能效率达到70%左右,振动控制效果达到65%以上。

Control effect of isolation control system with energy transducer in structural seismic response reduction was researched from the aspects of energy.The system can reduce structural vibration because of the energy transition,and the energy can be used for further structural control.The relation of transducer control force and isolator stiffness ratio was studied and the formula of control force was suggested The influence of different combination of energy transition device and isolator design on transition efficiency was explored.and the design process of the system was given.Based on the process presented,the transition efficiency can achieve 70%,the control effect can be over 65%.
