Analyse And Calculate Of Static Stability And Hydrodynamic Response Of Air Floating Structure

This article is to analyse the characteristic of static stability and hydrodynamic response of air floating structure. Theoretical analysis and numerical calculate are used in the article.A. Static StabilityBecause of having some result which got from some research work done before, the paper emphasized two aspects. One is to analyse the force act on the structure which was not mentioned very clearly before, and the other is to discuss the influence when do model experiments without regarding to air's similarity. We drew the force curve of the structure after calculation. Also calculated the influence arosed by circumstance pressure and brought forward a correct formula. B. Hydrodynamic ResponseWe imported a model so that wave force can be calculated by boundary element method. Based on the model we calculated an air floating platform which was structured by four canister. After knowing the wave force and a series of coefficients concerned, the hydrodynamic response of the structure can be got.After that we compared the response with the results got from experiments.
