초록

인구밀도가 증가하고 매년 고층건물의 수가 늘어나고, 대부분의 사람들이 하루에 엘리베이터를 이용하는 시간이 많아짐에 따라 일상생활 속에서 엘리베이터는 중요한 역할을 하고 있다. 매년 고층건물이 늘어남에 따라 고속 고층 승강기의 기술 요구 수준도 높아져 가고 있다. Carbon-fiber-reinforced plastics (CFRPs)는 높은 강성과 경량화 및 낮은 마찰력 등을 장점으로 하고 있으며, 엘리베이터용 wire rope에 매우 적합한 재료이다. 본 논문에서는 CFRP의 특성을 분석하기 위하여, wire rope와 CFRP UD의 인장 강도 및 수치 해석을 통한 벤딩 해석 비교를 진행하였다.

With increasing population density and high-rise expansion of buildings in recent years, elevators have become to play a pivotal role in our everyday lives as most people take an elevator several times even in a day. The elevator penetration and distribution rates in Korea have increased dramatically every year, and the emergence of skyscrapers leads to accelerating the development of elevator industry. Carbon-fiber-reinforced plastics (CFRPs) exhibit better mechanical and thermal properties than steel suitable for uses as elevator wire ropes. In this paper, in order to analyze the properties of CFRPs, the tensile strength of unidirectional (UD) CFRP wire ropes was characterized and finite element analysis was conducted for bending simulation. Simulation results were compared.
