Self-resetting SMA stranded wire composite magneto-rheological damping support
The invention discloses a self-resetting SMA stranded wire composite magneto-rheological damping support, and belongs to the technical field of energy dissipation and shock absorption. The self-resetting SMA stranded wire composite magneto-rheological damping support comprises an energy consumption module and a self-resetting module. A permanent magnet ring, a magnetic conducting ring and an inner pipe fixing baffle sleeve the middle of the inner pipe. An outer pipe inner boss, a left side sealing end plate, a right side sealing end plate and an inner circular pipe jointly form a sealing cavity, and the cavity is filled with magneto-rheological fluid. A boss is arranged in the outer pipe, and a groove is formed in the boss. A steel plate ring sleeves the end part of the inner pipe, SMA stranded wires are evenly arranged around the inner pipe by a circle, and the SMA stranded wires sequentially penetrate through the steel plate ring, the sealing plate and the boss and are fixed to the steel plate ring through an anchorage device. Through relative movement between the inner pipe and the outer pipe, a permanent magnet generates a variable magnetic field, and meanwhile, the damping size of magneto-rheological fluid in the sealing cavity is jointly adjusted through the change of the width of the damping channel; and no matter whether the support is in a pulled state or a pressed state, the SMA stranded wires are pulled, hyperelastic deformation occurs, a reset function is provided, and meanwhile, certain energy dissipation capacity can be achieved.
一种自复位SMA绞线复合磁流变阻尼支撑，属于消能减震技术领域。支撑包括耗能模块和自复位模块。内管中部套有永磁环、导磁环、内管固定挡板。外管内凸台、左侧密封端板、右侧密封端板、内圆管共同构成密封腔体，腔体内充满磁流变液。外管内部设置有凸台，凸台上设置有凹槽。内管端部套设有钢板环，绕内管一周均匀布置有SMA绞线，SMA绞线依次穿过钢板环、密封板、凸台，通过锚具固定在钢板环上。本发明通过内外管之间的相对移动，使得永磁体产生了变化的磁场，同时通过阻尼通道宽度的变化，共同调节密封腔体内的磁流变液的阻尼大小；无论支撑处于受拉还是受压状态SMA绞线均受拉，发生超弹性变形，提供复位功能同时能够具有一定的耗能能力。
