Abstract

The inner liquid pressure of an airtight tank in rolling motions is investigated by means of forced oscillation tests, and the simple method to estimate the inner liquid pressure is proposed. A rectangular solid tank, which is fully filled with water, was used in the forced oscillation test of rolling motion. The inner pressure variations in time were measured at several points on the inner walls of tank. Measured pressures are compared with the calculated ones, and estimation methods of the inner liquid pressure of the tank in rolling motion are studied based on the considerations of the origin of pressure.

강제 횡동요 실험을 통하여 동요하는 탱크의 내부압력을 폭정하고, 탱크의 내부압력을 추정하는 간단한 이론식을 제시하였다. 청수로 채워진 사각 탱크를 동요실험에 사용하였으며, 탱크의 안쪽 벽과 바닥에 압력게이지를 설치하여 내부압력의 시간변화량을 측정하였다. 측정된 탱크의 내부압력의 실험값과 이론식을 이용한 계산값을 비교하였다. 횡동요 하는 탱크내부의 압력을 구하기 위해 압력중심을 고려하여 추정하는 방법을 연구하였다.
