The invention discloses a self-resetting damper based on zinc-aluminum alloy and a manufacturing method thereof, and belongs to the technical field of engineering structure damping control. The device comprises a rectangular cylinder and a movable part located in the cylinder; and a connecting plate is arranged on a left end plate of the rectangular cylinder, and a rectangular hole is formed in a right end plate of the rectangular cylinder. After a zinc-aluminum alloy sheet is clamped an anti-buckling steel sheet, the Anti-buckling steel sheet is fixed between the left end plate and a movable plate; prestressed tendons are arranged between the movable plate and the end plates on the two sides; when the two ends of a damper do not generate relative displacement, the prestressing forces on the two sides of the movable plate are the same and are kept at a balance position; and when the damper is in compression or tension, the prestressed tendons provide self-resetting capacity and enable the zinc-aluminum alloy sheets to deform and consume energy. The damper is simple in structure and clear in force transmission; metal lead is replaced with the economical and environment-friendly zinc-aluminum alloy for energy dissipation on the basis of the self-resetting capacity; and the damper has good energy dissipation and shock absorption effects and the maintenance-free characteristics due to the high damping characteristics and room-temperature superplasticity characteristics of the zinc-aluminum alloy.
Description
technical field [0001] The invention relates to the technical field of engineering structure damping control, in particular to a self-resetting damper based on zinc-aluminum alloy and a manufacturing method thereof. Background technique [0002] The application of dampers in engineering structures can reduce structural vibrations caused by wind loads, earthquakes, etc., thereby improving structural safety and comfort. [0003] Among the common metal damper materials, mild steel has poor durability, while lead, which has excellent energy dissipation capacity and is stable, has a long half-life in the human body, causing serious harm to multiple organ systems and physiological functions of the human body. For example, the application document with the application number 201822248834.0 discloses a ring-shaped composite lead rubber damper. When the structure is subjected to an earthquake, the guide plate squeezes the lead rubber damping ball to dissipate energy. When the lead ru...
