Large-tonnage self-resetting inerter damper suitable for recoverable functional structure
The invention belongs to the technical field of earthquake resistance of civil engineering, and discloses a large-tonnage self-resetting inerter damper suitable for a recoverable functional structure, which comprises a connecting end, a rotating flywheel, a ball nut, a ball screw, a thrust bearing, a multilayer annular spring, an inner rod, a steel base plate, an outer sleeve and a fastening nut, the right end penetrates through the rotating flywheel, the ball nut and the thrust bearing in sequence and is fixedly connected with the inner rod; the left end of the inner rod is fixedly connected with the ball screw, and the right end of the inner rod sequentially penetrates through the steel base plate, the multi-layer annular spring and the fastening nut. According to the large-tonnage self-resetting inerter damper suitable for the recoverable functional structure, the vibration acceleration is reduced through the rotating flywheel with inerter synergy, large-tonnage damping force is provided through the multi-layer annular spring with the self-resetting capacity, and therefore displacement and the like are effectively reduced, and the fortification target that the function of an engineering structure can be recovered after an earthquake is achieved.
本发明属于土木工程抗震技术领域，公开了一种适用于可恢复功能结构的大吨位自复位惯容阻尼器，包括连接端、旋转飞轮、滚珠螺母、滚珠丝杠、推力轴承、多层环形弹簧、内杆、钢垫板、外套筒和紧固螺母，滚珠丝杠左端与连接端固结，右端依次穿过旋转飞轮、滚珠螺母和推力轴承，并与内杆固结；内杆左端与滚珠丝杠固结，右端依次穿过钢垫板、多层环形弹簧和紧固螺母。该适用于可恢复功能结构的大吨位自复位惯容阻尼器，通过具有惯容增效的旋转飞轮来减小振动加速度，通过具有自复位能力的多层环形弹簧提供大吨位阻尼力，从而有效地减小位移等，从而实现工程结构震后功能可恢复的设防目标。
