摘要：
Focusing on the suppression of liquid sloshing which may cause the elephant-foot buckling of storage tank walls, ring baffles were taken as a suppression device and its optimization design was carried out. An experimental research and a finite element analysis were performed on a 1:30 reduced-scale model. By using the model with or without baffles, the wave height, base shear force and tank wall pressure in both cases were investigated and compared. The reliability of the finite element simulation was verified by comparing the numerical results with the experimental ones. The study shows when the distance from liquid surface to the location of baffles relative to tank height is 0.125-0.225 and the baffle width relative to tank radius is near 0.15, the effect on suppressing wave is the most remarkable, additionally, near the bottom of tank, the stress reaches the maximum peak, which indicates the bottom region is just the elephant-foot buckling area. Thsi is of guiding significance for preventing failures. © 2017, Editorial Office of Journal of Vibration and Shock. All right reserved.
