Abstract

The invention discloses a multi-directional self-resetting shape memory alloy damper and a mounting method thereof. A damper top plate and a damper bottom plate are connected through supporting chainrods, the damper top plate and the damper bottom plate are symmetrically provided with a plurality of pulleys respectively, shape memory alloy wires penetrate through the pulleys and are symmetricallyarranged in a Z shape to form the damper of a cylindrical structure, and the shape memory alloy wires are pre-tensioned by rotating tension nuts arranged on the damper bottom plate, so that the initial stress of the shape memory alloy wires is in the middle section of martensite phase transformation. The multi-directional self-resetting shape memory alloy damper and a mounting method thereof havethe advantages that the structure is simple, and the installation is convenient; the multi-directional self-resetting shape memory alloy damper can be widely applied to passive control in the technical field of civil engineering and mechanical engineering to effectively reduce the vibration of structures or components and the residual deformation after strong vibration, and can be applied to basic vibration isolation and energy dissipation and shock absorption system to effectively control the vibration response of the upper structure under external vibration excitation.

Description

technical field [0001] The invention belongs to the technical fields of civil engineering and mechanical engineering, and in particular relates to a multi-directional self-resetting shape memory alloy damper and an installation method thereof, which can exert energy consumption and shock absorption at any angle in a plane. Background technique [0002] In modern technical research, vibration is mostly studied and controlled as a harmful effect on structures. In the field of civil engineering, the vibration of the structure is characterized by low vibration frequency and high vibration energy. Once it is damaged, it will bring huge loss of personnel and property. In the field of mechanical engineering, mechanical equipment inevitably has natural vibration and forced vibration during use, which affects the operation of various precision instruments and meters, and also causes noise pollution to the surrounding environment. Therefore, the control of vibration is extremely impo...
