Analyses of Sloshing and Seismic Responses for Cylindrical Vessel Containing Fluid

유체저장 원통용기의 슬로싱 현상 및 지진응답해석

Analyses of linear sloshing modes and seismic responses for cylindrical vessel containing fluid are performed by general finite element computer program, ANSYS. In order to examine the effectiveness of the sloshing analysis procedure, the calculated results are compared with experimental ones in the literature. Liquid sloshing effects in cylindrical LNG vessel are analyzed and the fluid-structure interaction effects are evaluated under the seismic loads. The sloshing frequencies calculated agree well with experimental results. The forces and moments for fixed and isolated LNG vessel are also calculated to evaluate the sloshing effects.
