| Research Abstract |
This research proposes the slice model that enables to estimate the dynamic fluid pressure due to the tank rocking motion with effects of asymmetrically uplift of the tank bottom plate by solving the velocity potential. In addition, employing an assumption that the tank contents are under the same action of the inertia force induced by the tank rock motion, the fluid contributing to the tank rock motion and rocking-bulging interaction are quantified. This research also develops a static analysis method based on the semi-analytic finite element method and clarifies that accurate calculation of uplift of the tank bottom plate needs all physical quantities related to the dynamical mechanism of the tank rock motion.
