摘要
将换能器安装在隔震结构的隔震层处,由结构和换能装置构成隔震换能结构体系,它既可以将地震输入给结构的部分能量转换成液压能,实现地震能量的转换,又能减小隔震层的水平位移,降低对隔震层的技术要求,降低造价。本文详细研究地震输给隔震换能结构体系的能量在体系各部分的分配,并与普通隔震结构对比,从能量的角度揭示隔震换能体系的换能控制原理。
The system constructed by equipping the transducer on the isolation layer of base-isolated structure can transform part of earthquake energy into hydraulic energy. It can realize the transition of the seismic energy, reduce the displacement of the isolated bearing and lower the cost. In this paper, the distribution of the seismic energy in the system is discussed in detail. To reveal the principle of energy transition control of the system, numerical simulation for a frame structure and the comparison with isolation system are carried out.
