모형 내압용기(耐壓容器)의 설계, 제작 및 압력시험에 관한 연구

Abstract

In this paper, the authors demonstrate a new idea for taking the place of the real pressure vessel test which should be carried out in a high pressure experiment unit before the real sea trial test. The idea is make a model pressure vessel as a replica of the real pressure vessel test that can reduce the cost of making a pressure vessel and large pressure experiment unit. The model pressure vessel was designed based on linear-elastic, buckling equations and Finite Element Analysis. The manufactured model pressure vessel was investigated and monitored while the pressure test was being conducted. After the test, the result and the validity of a model pressure vessel for a replica of the real pressure vessel test was studied.
