Composite bow type friction energy consumption variable tension shape memory alloy self-resetting damper
The invention relates to a composite bow-type friction energy consumption variable-tension shape memory alloy self-resetting damper, which aims to connect ultra-high molecular weight polyethylene fibers and shape memory alloy wires in series and combine the ultra-high molecular weight polyethylene fibers and the shape memory alloy wires with piezoelectric materials to form a bow-string type mechanism so as to realize tension-compression two-way friction energy consumption, and an outer sleeve and a right connecting piece are connected into a whole after being welded. Bolts penetrate through the bolt holes to be connected with the extrusion holes in the friction blocks. Bolts pass through the bolt holes to extrude and connect the friction blocks and the friction steel plate; the two sides of the sliding rod are connected through the check block, the friction steel plates are connected to the upper side and the lower side of the sliding rod and move in a sliding groove of the outer sleeve along with the pull rod, the left sliding block and the right sliding block are connected to the two sides of the fixed check block respectively and connected through the baffles, and the left baffle and the right baffle are connected through the prestressed tendons through the anchor bolts. The left end plate is connected with the sliding rod and then welded with the left connecting piece into a whole, and the upper end and the lower end of the ultra-high molecular weight polyethylene fiber and the upper end and the lower end of the shape memory alloy wire pass through the connecting bolts to form a closed loop and are connected into a whole.
