The Dynamics Of The Vehicle Container

In our country, oil tankers are the 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 vibration will become more important. The vibration of fluid-solid 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 cylindrical tankers 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, Achievements and primary study methods on some major research topic are discussed in detail. The tendency of liquid-solid interaction mechanics development in the future is also analyzed and suggested.2,The model of the oil tankers' fluid-solid coupled system is founding. The equation based on the finite element method and the expressions of natural frequency and modal shape are getting.3 , The static properties of oil tanker with different height and free surface of fluid are analyzed. And the solutions are compared in the end.4,The modes of cylindrical oil tankers with different height and free surface of fluid are calculated with finite element software ANSYS on the basis of the fluid-solid coupled theory. The natural frequencies and the modal shapes are obtained.5, The oil tanker's response are calculated when it get the impulsive excitation and harmonic excitation.The static and dynamic mechanical character, response 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 accident, prolonging the life, improving the security and decreasing the loss. It also can help design and produce the new oil tankers according the results.
