Abstract

This study is door safety device for the structural analysis are described. Recently emerged as a key point of the door safety and increase the need of a door safety device. In order to improvement this inconvenience, the door safety device was design and structural analysis by using CATIA. CATIA utilizes door safety device element model for displacement, stress and strain energy were obtained. Consideration of door open angles were $95^{\circ}$, $100^{\circ}$, $105^{\circ}$, $110^{\circ}$, $115^{\circ}$, $120^{\circ}$. These results will be provided to develop new concepts of door safety device as initial data.

모든 건축물에 사용되고 있는 도어는 안전장치를 부착하지 않아 사고가 빈번하게 발생하고 있으며 어린이에게는 치명적인 손 끼임 사고로 이어진다. 이러한 사고를 방지하기 위한 도어 안전장치를 개발하기 위하여 기존의 도어 안전장치에 대하여 구조해석을 실시하였다. 기존 도어 안전장치의 안전성을 검증하기 위하여 CATIA를 활용하여 모델링하고 도어의 개폐각도는 $95^{\circ}$, $100^{\circ}$, $105^{\circ}$, $110^{\circ}$, $115^{\circ}$, $120^{\circ}$를 고려하였으며 구조해석의 결과로서 변형량, 응력, 변형률 에너지를 구하였다. 이러한 해석결과는 새로운 도어 안전장치를 개발하기 위한 초기자료로 활용되었으며 어린이가 손이 끼이지 않도록 경첩부에 설치하고 반대면은 플라스틱 커버 형태로 개발하여 손 끼임을 방지한다
