Bionic Investigation on Multiple Intersecting Egg-shaped Pressure Hulls
摘要
Abstract
Bionic design of multiple intersecting egg-shaped pressure hulls was carried out based on goose egg shell.Firstly,egg-shaped function was established according to a series of biological ex-periments of egg shells.Then,multiple intersecting egg-shaped pressure hulls in deep sea were de-signed.Numerical models with 2,3,4,5,6 eggshells were established.Critical buckling loads,yield loads and buoyancy factors of these hulls were studied.Finally,effects of the main geometric parame-ters on the performances of the multiple intersecting egg-shaped pressure hulls were analyzed using orthogonal experimental design.The results show that Kitching function is the best egg-shaped func-tion describing goose egg meridian.The length-to-eccentricity ratio is as 45,and the egg shape index is as 0.69.The critical buckling loads of the egg-shaped pressure hulls are larger than yield loads,indica-ting that strength is the main factor of the structural design.The number of eggshells has little influ-ence on the yield loads and buoyancy factors,while the shell thickness has a great influence on them. The geometrical parameters of the rib have little influence on the buoyancy factors but great on the yield loads.关键词
