Problems solved by technology

However, the pure high-damping rubber shock absorber has small stiffness, and the deformation is too large after compression; while the laminated rubber shock absorber is too rigid, the deformation is too small after compression, and the energy dissipation effect is not significant.
Therefore, this type of shock absorber has many restrictions in engineering applications.

Abstract

The invention discloses a damper made with a high damping rubber cylinder and wrapped with a shape memory alloy wire in segments, and belongs to the field of engineering structural damping control. High damping rubber and the shape memory wire are high-elasticity and high-damping materials, and the combination thereof can satisfy energy dissipation requirements of various earthquake intensities. The high elasticity of the shape memory wire can significantly improve the axial bearing capacity of a pure rubber body, and the combination of the two high-elasticity materials enables the damper to possess better restoring force. The shape memory alloy wire wraps the high damping rubber cylinder in segments. The axial stiffness of the damper is adjusted by adjusting the cross-sectional area and length of the high damping rubber cylinder, the diameter of the shape memory alloy wire, the number and width of wrapped segments and the spacing between every two wrapped segments so that axial stiffness requirements of the damper at different positions are satisfied. The damper made with the high damping rubber cylinder and wrapped with the shape memory alloy wire in segments has the advantage that the installation is simple without the need for any other connectors; and the damper can be used in reinforcement projects of newly-built structures and old structures, and can be applied to the field of the engineering structural damping control.

Description

technical field [0001] The invention belongs to the field of shock-absorbing control of engineering structures, and relates to a shock-absorbing control device, in particular to a high-damping rubber cylinder segmented outer-wound SMA capable of suppressing the structural vibration response of engineering structures under earthquake action Wire damper. Background technique [0002] High-damping rubber material is a kind of energy-dissipating shock-absorbing material with excellent performance. Using its superelasticity and high damping performance, high-damping rubber dampers can be made for structural vibration control. It is an energy-dissipating shock-absorbing device commonly used in engineering. , such as pure high damping rubber shock absorbers, laminated rubber shock absorbers, etc. However, the pure high-damping rubber shock absorber has small stiffness, and the deformation is too large after compression; while the laminated rubber shock absorber has too high stiffn...
