Automatic Restoration and Self-Healing Damper System Utilizing Smart Material

摘要

A damper system is disclosed. The damper system of the present invention comprises: a guide unit having a predetermined length along an imaginary load action line parallel to a direction in which a tensile force or a compression force acts; A first moving unit coupled to one side of the guide unit and reciprocating in parallel with the load action line; A second moving unit spaced apart from the first moving unit and coupled to one side of the guide unit and reciprocating in parallel with the load action line; A deformation unit made of a shape memory alloy to connect the first moving unit and the second moving unit and to be tensioned and recovered along a direction parallel to the load action line; An operation unit configured to pull the second mobile unit to move the second mobile unit away from the first mobile unit, and to push the first mobile unit to move the first mobile unit away from the second mobile unit; A first elastic body made of a polyurethane elastic body, the first elastic body being deformed when the operating unit pushes the first moving unit; And a second elastic body which is made of a polyurethane elastic body and which is compressively deformed when the operating unit pulls the second moving unit, and when the first moving unit and the second moving unit move away from each other, the deformation unit is tensioned. It is done. According to the present invention, when the tensile force is applied to both ends of the damper device and the compressive force is applied to the deformation unit is tensioned, the deformation prediction of the deformation unit is easy to design the damper device for shock absorption, vibration and displacement control It is possible to provide a damper device having a stable structure, and to provide a damper device capable of maximizing a buffering effect, shock absorbing and restoring effect, including a superelastic shape memory alloy and a self-healing thermoplastic polyurethane.
