Problems solved by technology

However, the axial compressive strength and equivalent viscous damping of SMA are not enough to make it the only material for shock absorbers, and the commonly used shape memory alloy shock absorbers have high cost, large amount of SMA, complex structure, and low energy consumption efficiency. The problem
High-damping rubber material is an energy-dissipating shock-absorbing material with excellent performance. It has the characteristics of high elasticity, high damping, and convenient application. Most of the devices are used in compression structures, and the application range is limited

Abstract

The invention provides a damper with shape memory alloy stranded wires penetrating through a high-damping rubber body, and belongs to the field of engineering structure seismic control. The high elasticity and the shape memory effect of the shape memory alloy stranded wires enable the damper to have the good tensile capacity, the deficiency that high-damping rubber is insufficient in tensile capacity is overcome, and the damper is made to have better resilience. Serving as a super-elastic material, the high-damping rubber has a good compressive property, and the compressive property of the damper is improved. The shape memory alloy stranded wires penetrate through the high-damping rubber body, the axial rigidity of the damper is adjusted by adjusting the sectional area and the length of the high-damping rubber body and the number, the diameter and the pre-tensioning degree of the shape memory alloy stranded wires, and energy dissipation damping requirements under earthquakes with different intensities can be met. The damper is easy to install, other connecting pieces are not needed, and the damper can be used for reinforcement projects for newly-built structures and existing structures as well as being used for the field of seismic control for engineering structures.

Description

technical field [0001] The invention belongs to the technical field of structural damping control, and relates to a damper with shape-memory alloy stranded wire inside a high-damping rubber body, which can inhibit the structural vibration response of engineering structures under different intensity earthquakes, and achieve energy consumption. The effect of shock absorption. Background technique [0002] As a new type of functional material, shape memory alloy (SMA) has the advantages of shape memory effect, superelasticity, high damping, durability, corrosion resistance and self-resetting, and has obvious advantages in shock absorption and energy consumption of engineering structures. However, the axial compressive strength and equivalent viscous damping of SMA are not enough to make it the only material for shock absorbers, and the commonly used shape memory alloy shock absorbers have high cost, large amount of SMA, complex structure, and low energy consumption efficiency. ...
