The Optimization of the Hull Form with the Minimum Wave-Making Resistance Based on Potential Flow Theory

Abstract

Based on the Michell integral method and the Rankine source method, the parameters of the double-triangle ship modification function are used as the design variables. Under the condition of ensuring the drainage volume as the basic constraint, the optimal design model of nonlinear programming method (NLP), traditional genetic algorithm (SGA), and niche genetic algorithm (NGA) are established by considering the influence of tail-viscosity separation. The whole ship linear optimization design program with independent intellectual property rights is developed, and the effectiveness of the program is verified through experiments. The research results have important guiding significance to promote the ship design from the traditional experience mode to the knowledge-based mode.
