Shearing type STF damper
The invention provides a shearing type STF damper. The shearing type STF damper comprises an upper connecting plate, steel teeth, a steel sleeve, an upper cover, a baffle and a steel spacer. The steel sleeve is provided with a plurality of steel spacers, and a blocking door is welded to the steel sleeve and fixedly connected with the steel spacers. The steel teeth are provided with a plurality of tooth pieces and inserted into gaps of the steel spacers, baffles used for limiting the steel teeth are arranged on the upper portions of the steel spacers, and the baffles are fixedly connected with the steel sleeve. The upper cover is fixedly connected with the top end of the steel sleeve; the waist of the upper cover is provided with an open slot for the steel teeth to pass through; the steel teeth are in dry friction sliding fit connection with open slots, and the tops of the steel teeth are fixedly connected with the upper connecting plate. According to the shearing type STF damper, due to the fact that the flowing space of STF damping fluid is extremely small compared with the space occupied by the steel teeth, a large sliding speed can be generated, and STF can conveniently exert the shear thickening effect. Along with the increase of the shearing rate, the STF viscosity is rapidly increased, so that the impact resistance and vibration isolation of an engineering structure are realized. The damper has the advantages of being novel in structure and clear in construction, and is a safe and efficient damper.
本发明提供了一种剪切型STF阻尼器，包括上连接板、钢齿、钢套筒、上盖、挡板、钢隔片；钢套筒设有多个钢隔片，钢套筒焊接有挡门，挡门与钢隔片固接；钢齿具有多个齿片，钢齿插入钢隔片的空隙内，在钢隔片上部设有用于限位钢齿的挡板，挡板与钢套筒固接；上盖与钢套筒顶端固接，上盖腰部设有供钢齿穿过的开口槽；钢齿与开口槽干摩擦滑动配合连接，钢齿顶部与上连接板固接。由于STF阻尼液可流动空间与钢齿所占空间相比极小，故可产生较大的滑动速度，便于STF发挥剪切增稠效应。随着剪切速率的增加，STF粘度迅速增大，从而实现工程结构抗冲隔振。该阻尼器具有结构新颖、构造明确的优点，是一种安全、高效的阻尼器。
