【摘要】 本文提出了用于结构振动控制的电液式可变刚度装置。该控制装置由可变刚度构件、液压集成块和电子控制盒组成。可变刚度构件的结构形式，可根据具体情况在结构设计时确定；液压集成块主要由双杆活塞－油缸和电磁阀组成；电子控制盒是一个体积很小的硬件盒子，它接受控制传感器所测试的振动信号。根据变刚度半主动结构振动控制的控制律，进行控制运算及处理，输出开关信号传输给电磁阀，实现可变刚度构件的ＯＮ／ＯＦＦ状态控制。由于该控制装置实现了全部硬件化，并且具有结构简单、造价低、健壮性好等优点，便于在实际工程中应用。更多还原

【Abstract】 In this paper,the electro-hydraulic variable stiffness system(EHVSS)is proposed as a structural vibration control system.The EHVSS is composed of a variable stiffnesscomponent,a mechanical equipment and a electronic controller.The mechamical equipmentconsists of a cylinder and two electro-magnetic valves.According to the structural vibrationresponse,the variable stiffness unit alters its on/off state in such a way as to absorb and releasethe motion energy of the controlled structure.Theoretical analysis and shacking table test showthat the EHVSS is capable of alleviating efficiently the vibration of structures subject to bothstrong winds and earthquakes.更多还原
