Zusammenfassung:The present invention relates to a smart damper capable of compensating for thermal displacement caused by a temperature change of a pipe and absorbing impact by controlling vibration, and more specifically, relates to a pipe vibration control smart damper capable of compensating for thermal displacement, which comprises a vibration buffering part and a thermal displacement compensation part, wherein the vibration buffering part is made of a polyurethane elastic member and performs compensation of vibration and thermal displacement, allows the thermal displacement compensation part having a compression spring and an impact sleeve positioned on both sides based on the vibration buffering part to primarily compensate for thermal displacement before performing the compensation for thermal displacement by the vibration buffering part. As such, vibration or impact is stably absorbed by compensating for vibration and thermal displacement through the two steps of vibration buffering and thermal displacement compensation. Compared to a conventional damper, the smart damper has a simple structure, uses low-cost material, and has superior durability, thereby saving costs for production and maintenance. A shape-memory alloy wire is installed such that the compression spring and polyurethane elastic member have high capability of restoration. 본 발명은 배관의 온도변화에 의해 발생하는 열변위를 보상할 수 있고, 진동을 제어하여 충격을 흡수할 수 있는 스마트 댐퍼에 관한 것으로, 보다 상세하게는 진동 완충부와 열변위 보상부로 이루어지되 진동 완충부는 폴리우레탄 탄성 부재로 진동 및 열변위 보상을 실시하며, 진동 완충부의 열변위 보상 실시전 상기 진동 완충부를 기준으로 양쪽에 압축 스프링과 임팩트 슬리브로 구성된 열변위 보상부가 일차적으로 열변위를 보상하는 열변위 보상이 가능한 배관 진동제어 스마트 댐퍼로 2단계 걸쳐 진동 및 열변위 보상을 진동 완충부와 열변위 보상부로 실시하여 진동 또는 충격을 안정적으로 흡수하고, 종래의 댐퍼에 비해 구성이 간단하고, 재료의 가격이 저렴하며, 내구성이 우수하여 생산 및 유지관리 비용이 절감되며, 형상기억합금 와이어를 설치하여 압축 스프링과 폴리우레탄 탄성 부재의 복원능력이 높다.
