一种新的隔震换能控制装置及其应用

提出了一种新的结构振动控制装置，该装置具有隔震换能和主动控制的双重功能。将该装置安装在建筑结构的隔震层处，在地震、大风等外荷载激励下结构的隔震层将产生较大的相对运动，由此可以驱动该控制装置发挥作用。此时由计算机控制，根据控制效果的需要可以使得该装置在隔震换能和主动控制的两种工作状态之间适时切换。本文建立了该装置的数学模型，提出了建筑结构隔震换能控制系统的分析方法和控制策略，并给出了一个结构控制仿真分析的算例。

A New Type of Control Device with Energy Transducer and Its Application

A new structural control device is proposed in the paper. The control device has two working status: one is isolation and energy transform, the other is active control. The motion of the isolation layer of a structure excited by strong winds or earthquake drives the control device to work. The control device that equipped in the layer can change its working status under the control command of a computer. The control device combines the advantages of isolation and active control: when it works in isolating status, it can reduces the responses of the structure, while it can transform part of the earthquake input energy into hydraulic energy; when it works in active control status, it can using the transformed hydraulic energy as power supply. The new structural control device might be a more effective structural control apparatus. The mathematical model of the control device is presented in the paper, and a structural control simulation is given as an example.
