Optimum head design of filament wound composite pressure vessels using a hybrid model of FE analysis and inertia weight PSO algorithm

Filament wound composite pressure vessels are widely used in industrial applications. Determination of the optimal head profile has been recognized as one of the most important design issues. This paper presents the optimum design of head contours for a filament wound composite pressure vessel using a hybrid model of finite element analysis and inertia weight particle swarm algorithm. Geometrical limitations, winding conditions and the Tsai-Wu failure criterion have been used as optimization constraints. The objective is to maximize the shape factor using present optimization technique. An actual design example taken from available literature is used as a case study. Results indicate that the dome contours using the suggested method shows stronger structure and greater internal volume. This confirms that the proposed model can efficiently define the optimal dome shape.
