초록

본 연구는 ESS 물탱크 패널의 최적 절곡깊이 산정에 관한 연구이다. 스테인레스 패널에 프레스 작업을 하게 되면 엠보싱부분의 패널 두께가 감소되며, 감소된 패널 두께는 체적보존의 가정을 이용하여 계산하였다. 해석을 위해 STS304 재료를 사용하였으며, 유한요소해석을 통해 결과를 산출하였다. 유한요소해석결과 아치엠보싱 패널의 최적 절곡깊이는 70~90mm로 평가 되었으며, 피라미드 엠보싱패널은 150~200mm로 평가되었다. 최적절곡깊이의 제안 값은 ESS 물탱크 패널의 경제적 설계에 효과적일 것으로 판단된다.

This study is on the optimal rise depth of embossed panel for the ESS water tank. The thickness of panel is reduced at pressing operation, it could be calculated by volume conservation condition. The analysis of panel using STS304 material conducted by FEM. As a result of structural analysis, it was found that the optimal rise depth of arch embossed panel is recommended to be 70~90mm and the optimal rise depth of pyramid embossed panel is recommended to be 150~200mm. The proposed value of optimal rise depth could be a useful to the economic design of ESS water tank panel.
