Abstract

The invention discloses a multi-directional laminated variable-stiffness shape memory alloy damper and a mounting method thereof. A plurality of damper intermediate plates are laminated between a damper top plate and a damper bottom plate to form the damper of a cylindrical structure, and shape memory alloy wires are horizontally and symmetrically arranged between any vertically adjacent laminatedplates. The multi-directional laminated variable-stiffness shape memory alloy damper and the mounting method thereof have the advantages that the problems of smaller stroke, poor reset performance, poor durability, poor high and low temperature resistance and the like of an existing damper are solved, the structure is simple, the installation is convenient, and the multi-directional laminated variable-stiffness shape memory alloy damper can be widely applied to passive control over structures in the technical field of civil engineering and effectively reduces the vibration of structures or components and the residual deformation after strong vibration.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a multi-directional laminated variable stiffness shape memory alloy damper and an installation method thereof. Background technique [0002] In the field of civil engineering, structures are inevitably subjected to various types of vibration loads, such as wind loads, earthquake loads, and blast impact loads. Traditionally, anti-seismic (vibration) structures usually dissipate the energy of vibration loads at the cost of damage to structural components. For some structures with special requirements (such as nuclear power plant casing, liquid storage tank, etc.), the damage of components and even the excessive structural vibration response are unacceptable, so the control of structural vibration is extremely important. Shock isolation (vibration) and energy dissipation shock (vibration) technology is one of the commonly used technical means in the field of s...
