Experimental Study on Steel Plate Forming by Line Heating
Abstract
선체 외판을 구성하는 곡면의 가공은 선박생산에서 대단히 중요한 위치를 차지하고 있는 공정 중 하나이다. 선수미부에서 볼 수 있는 두 축 방향으로 곡률이 있는 곡면의 ?嚥? 현재 선상가열법이나 삼각가열법에 의한 열가공법을 적용하여 가공하고 있다. 본 논문에서는 선상가열법에 의한 곡가공에 대한 실험을 수행하고 분석한 결과를 다루었다. 여기에서는 횡방향 뿐만 아니라 종 방향으로도 곡률을 갖고 있는 곡면 형상의 가공에 사용되는 삼각가열을 구현하기 위해 선상가열법을 변형하여 그 효과를 나타낼 수 있는 실험을 수행하였다. 다수의 실험모델에 대한 실험결과를 가공의 효과 측면에서 분석한 결과 현장에서의 삼각가열의 효과를 변형된 선상가열법을 적용해서 구현할 수 있음을 알 수 있었고 또한 안형곡면의 가공에 효과적으로 적용될 수 있음을 알 수 있었다.
Plate forming is well known process as one of the most important in ship buildings. For the curved plate in bow and stern part which has curvatures in two directions is formed by applying heating method such as line and triangular heating methods. This paper is concerned with the experimental study of plate forming by line heating. In this study the traditional line heating method is modified to simulate the triangular heating effect for the pillow shape curved surface which has longitudinal curvatures as well as transverse curvature. This modified line heating method has been applied to several plate models and the results are analysed from view point of efficiency of plate forming. From the present study it has been found that the effect of triangular heating can be simulated by applying the modified line heating method and it can be effectively applied to forming of pillow shape curved surface.
