STF rotary damper based on ball screw
The invention belongs to the field of engineering vibration control, and particularly relates to a STF rotary damper based on a ball screw. The STF rotary damper comprises a small steel sleeve, a nut, the ball screw, a rotating disc, a static disc, a large steel sleeve and shear thickening fluid, wherein one end of the ball screw extends into the small sleeve through the nut, the other end of the ball screw extends into the large sleeve and is welded to the rotating disc, the static disc is arranged on the inner wall of the large sleeve, the rotating disc and the static disc are in cross connection with each other at an interval, and the large sleeve is filled with the shear thickening liquid which fills a gap between the static disc and the rotating disc. The rotary damper is composed of the shear thickening fluid and the ball screw fully utilizes the advantage of vibration energy of an STF passive rapid high-consumption structure, and the rotary damper is simple in structure, safe and efficient.
本发明属于工程振动控制领域，具体涉及一种基于滚珠丝杆的STF旋转阻尼器，包括小钢套筒、螺母、滚珠丝杆、旋转盘片、静止盘片、大钢套筒、剪切增稠液；所述滚珠丝杆一端通过螺母伸入到小套筒内，另一端伸入到大套筒内，并与旋转盘片焊接；所述大套筒内壁有静止盘片，旋转盘片与静止盘片保持间隙相交叉连接；所述大套筒内部填充剪切增稠液充斥于静止盘片与旋转盘片的间隙内。本发明为剪切增稠液和滚珠丝杆组成的旋转阻尼器，充分利用STF被动快速高耗结构振动能量的优点，本发明是构造简单，安全高效的阻尼器。
