Abstract

The invention discloses a sliding type performance-adjustable shape memory alloy damper belonging to fields of structure damping control, disaster prevention and reduction and protection. In order to solve the problem of incapability of regulating rigidity and energy consumption capacity of the traditional shape memory alloy damper, the sliding type performance-adjustable shape memory alloy damper comprises shape memory alloy wires arranged on at least one clamp I and at least one clamp II, a runner plate provided with a groove, and a sliding block arranged in the groove; and the runner plateand the sliding block are provided with a plurality of screw holes, the lower end of the clamp I is fixed on the sliding block, and the lower end of the clamp II is fixed on the runner plate. The sliding type performance-adjustable shape memory alloy damper can be mainly used for reset and energy consumption vibration attenuation (shock) after structure deformation, can also be used as a structure member for generating a nonlinear restoring force and can be used in simulation and test research of a structure nonlinear power behavior, and has the advantages of stable performance, simple structure and easiness in disassembly.

Description

technical field [0001] The invention relates to the fields of structure damping control, disaster prevention and mitigation, and protection, in particular to a sliding type performance-adjustable shape memory alloy damper, which is mainly used for reset after structural deformation and energy consumption and vibration reduction (shock). The device can also be used as a structural component that generates nonlinear restoring force for simulation and experimental research on nonlinear dynamic behavior of structures. Background technique [0002] Shape memory alloy dampers can be used for structural reset and energy dissipation shock absorption control. This type of damper mainly uses two characteristics of shape memory alloys—superelasticity and shape memory. Among them, energy dissipation shock absorption depends on its super Elastic properties, shape memory properties facilitate the reset of structures with residual deformation. After the design and installation of the shap...
