Abstract

The invention discloses a shape memory alloy damping device with a self-monitoring function, and belongs to the fields of structural damping control and disaster prevention and reduction protection. The damping device comprises a steel sleeve connected to a foundation or a structure through a connector, an inner steel cylinder partially arranged in the steel sleeve and at least one pair of clamps, wherein the steel cylinder is provided with at least one chute and a plurality of screw holes; the inner steel cylinder is provided with a plurality of screw holes; one of the paired clamps passes through the chute and is arranged on the screw holes of the inner steel cylinder, and the other clamp is arranged on the screw holes of the steel sleeve; and a shape memory alloy wire is connected between one clamp and the other clamp in the paired clamps. The damping device can be used for energy dissipation damping and control of the structure, can also be used for monitoring the performance change of an energy dissipation device in real time, has the advantages of good energy dissipation damping effect, simple structure and the like and is monitored in real time and easy to assemble and disassemble.

Description

technical field [0001] The invention relates to the field of structure damping control and disaster prevention and mitigation protection, specifically a shape memory alloy damping device with automatic monitoring of its damping performance, which is mainly used for energy consumption and shock absorption of structures under dynamic action and can monitor damping in real time The time history of the power consumption provided by the device during the energy consumption process, and the device can also be used for simulation and experimental research on the nonlinear behavior of structures. Background technique [0002] Due to its shape memory and superelastic properties, shape memory alloys can be used as a damping device for energy dissipation and vibration control of civil structures and mechanical engineering structures. The general shape memory alloy damping device will degrade the energy dissipation effect due to loose connection and other reasons during use. It is of gr...
