Light Tanker Tank Kinetic Analysis

In our country, oil tankers are mainly tool for the transport of oils. Previously the containers carried by trains were researched and analyzed in statics. With the train's speed improving recently, the containers will get stronger dynamic force. The problem of structure and fluid coupled system not only is likely to lead to the instability of system but also can make the containers destroy because of the additional compression reduced by the sloshing of fluid, so this problem should particular research and analyze. In this paper, the tankers of G₆₀ and G_70B are selected as the researched model. The software ANSYS is the tool for analysis. The fluid-solid coupled problem of oil tankers will be calculated and analyzed.The main works of the thesis are finished as follows:1) The elementary theory and method about the fluid-solid coupled system are introduced.2) The software ANSYS are introduced.3) The static properties of G₆₀'s and G_70b's tanker with different height and free surface of fluid are analyzed.4) The modes of G₆₀'s and G_70b's tankers with different and free surface of fluid are analyzed. The natural frequencies and the modal shapes are obtained.5) The harmonic response of G₆₀'s and G_70b's tankers with different and free surface of fluid are analyzed in the vertical and cross direction.6) The transient state of G₆₀'s and G_70b's tankers with different and free surface of fluid are analyzed when trains are brakedThe static and dynamic mechanical responses are studied synthetically in the thesis, so the fluid-solid coupled rules about the oil tankers are obtaining at last. It is important in discovering G₆₀'s and G_70b's tanker incipient fault, prolonging tanker life, improving the tanker security and decreasing the loss. It also can help design and produce the new oil tankers according to the results.
