Study on Floating Properties and Stability of Air Floated Structures     

BIE  Shean 《中国海洋工程》2002,16(2):263-272

In this paper, the buoyancy, kinetic properties and stability of air floated structures have been studied by theoretical and experimental methods. The ecpjations for calculation of the buoyancy of the air floated buoy are derived according to the Boyler law and the equilibrium equations of the air floated structure are established. Through simplification of the air floated structure as a single freedom rigid body and spring system, the natura! period of heaving and some kinetic properties are discussed. In the stability analysis, the formulas for calculation of the meta centric height are presented. The theoretical results are in good agreement with the data observed from the model test and prototype test. The air buoyancy de-crease coefficient presented in this paper has a large influence on the floating state, stability and dynamic properties of the air floated structure. The stability of the air floated structure can also be judged by the parameter of meta centric height, and calculations show that t  相似文献
