【摘要】 针对目前隔震体系尚不能减小竖向地震反应的缺陷,提出并研制了采用碟形弹簧的竖向半主动隔震装置。竖向半主动隔震装置是由碟形弹簧和外套油缸组成的,且由电磁阀控制油缸内油体与外接蓄油箱内油体间的油路,可实现竖向半主动隔震控制,提出了竖向隔震控制的半主动策略,结合水平隔震支座可实现三维隔震。通过振动台地震模拟实验,验证了三维隔震体系的效能,该研究对高烈度地区隔震技术的改善具有应用参考价值。更多还原

【Abstract】 In this paper,in view of the limitation that the preset base isolation system can not decrease the vertical seismic response,a kind of vertical semi-active isolated device with disk spring was developed.The vertical semi-active isolated device is made up of oil cylinder within disk spring and electromagnetic valve that controls the oil route between the oil cylinder and oil box,then achieves the vertical semi-active isolation,and draws up a semi-active control strategy suited to vertical semi-active isolated control.Combining vertical semi-active isolated device with horizontal isolated bearing can achieve three-dimensional isolation.The control efficiency of three-dimensional isolation system was validated through the shaking table tests,this research is a help to reform the isolation technique in a high seismic intensity zone.更多还原
