Self-resetting SMA-viscous vibration reduction damper
The invention discloses a self-resetting SMA-viscous vibration reduction damper. The damper comprises a head connecting lug ring, a piston rod, a head sealing cover, a piston, a viscous damping medium, a cylinder body outer wall, a middle sealing cover, a spring pressing plate, an SMA spring, a guide hollow rod, a tail sealing cover and a tail connecting lug ring. The self-resetting SMA-viscous vibration reduction damper provided in the invention has advantages and positive effects that 1, most of input vibration energy can be dissipated; 2, the SMA spring can dissipate low-frequency or ultrahigh-frequency vibration energy, and meanwhile, the piston can be recovered to an original position to eliminate residual deformation; 3, the rigidity of the damper can be adjusted by adjusting pre-pressure of the pre-pressing spring as required; and 4, mounting and dismounting are simple and maintenance is easy.
一种自复位SMA‑粘滞减振阻尼器。其包括头部连接耳环、活塞杆、头部封盖、活塞、粘滞阻尼介质、缸体外壁、中部封盖、弹簧压板、SMA弹簧、导向空心杆、尾部封盖和尾部连接耳环；本发明提供的自复位SMA‑粘滞减振阻尼器具有的优点和积极效果是：1.可以耗散大部分输入振动能量；2.SMA弹簧可以耗散低频或超高频振动能量，同时可以恢复活塞至原来位置以消除残余变形；3.可根据需要通过调节预压弹簧预压力的方法来调整阻尼器刚度；4.安装拆卸简单，易于维修维护。
