각형 압력탱크 개발 연구 = A Study on Prismatic Pressure Vessel

다국어 초록 (Multilingual Abstract)

Through a comparison between the cylinder-shape pressure vessel that was previously being used and the prismatic-shape pressure vessel with increased volume efficiency, it was analyzed and interpreted the problems that had arisen so far during the development of the prismatic-shape pressure vessel. Conditions involving volume efficiency, the comparison of stress level when the thickness of plates were the same, and production costs were taken into consideration. In the process of analyzing strengths and weaknesses the prismatic-shape pressure vessel had, it was discovered that multiple pressure vessels were more advantageous than a single pressure vessel in terms of production costs. In addition, it was found the way to lower the stress level of the prismatic-shape pressure vessel by altering the thickness of its plate or installing a stiffener. It was figured out that additional research about effect of stiffener shape and thickness, shape of plate junction and junction stiffener were needed.
