Shape optimization of thin-walled pressure vessel end closures

摘要

In this paper the problem of shape optimization of thin-walled pressure vessel heads is investigated. Shape of a meridian which minimizes the functional containing a depth and capacity of a vessel closure is sought. The meridian is approximated either by the convex Bézier polynomial or by functions with free parameters. Domes consisting of both two- and one-arc are considered. The optimal solutions are obtained using the simulated annealing algorithm.
