Viscous damping wall shock absorption system with butterfly plate
The invention discloses a viscous damping wall shock absorption system with a butterfly plate. The viscous damping wall shock absorption system comprises an upper connecting plate, a lower connecting plate, an outer steel box, a damping steel plate and the butterfly plate. The upper surface of the lower connecting plate is connected with an outer steel box, and viscous damping liquid is contained in the outer steel box. A vertical damping steel plate is connected to the lower surface of the upper connecting plate, and a plurality of butterfly-shaped plates are hinged to the two sides of the damping steel plate and soaked in the viscous damping liquid. When an earthquake occurs, the damping steel plate horizontally moves in the outer steel box, the damping steel plate drives the butterfly-shaped plate to rotate, the butterfly-shaped plate drives the viscous damping fluid to do accelerated motion, and the damping steel plate shears the viscous damping fluid back and forth for friction energy dissipation. According to the butterfly-shaped plate hinged to the damping steel plate, the shear face is increased, the viscous damping fluid is dense in streamline at the tip end of the butterfly-shaped plate, the velocity gradient of the viscous damping fluid is improved, the damping force is greatly improved, earthquake energy can be effectively consumed, and the response of the structure is reduced.
本发明公开了一种设有蝶形板的粘滞阻尼墙减震系统，包括上连接板、下连接板、外钢箱、阻尼钢板和蝶形板。下连接板的上表面连接有外钢箱，外钢箱内装有粘滞阻尼液。上连接板的下表面连接有竖直的阻尼钢板，阻尼钢板的两侧均铰接有若干蝶形板，蝶形板浸泡在粘滞阻尼液中。地震时，所述阻尼钢板在外钢箱内水平运动，阻尼钢板带动蝶形板转动，蝶形板带动粘滞阻尼液加速运动，阻尼钢板对粘滞阻尼液来回剪切进行摩擦耗能。铰接于阻尼钢板上的蝶形板，不仅增加了剪切面，还使得粘滞阻尼液在蝶形板尖端流线密集，提高了粘滞阻尼液的速度梯度，大幅提升了阻尼力，能有效消耗地震能量，降低结构的响应。
