Guobin Li · Chuanbo lixue · 2008
Based on the characteristic that the parameters of the stabilizer fin play an important role in the longitudinal motion performance of SWATH,the multi-objectives optimization mathematical model of the stabilizer fin is established in this paper. Then,the multi-objectives genetic algorithm based on Pareto sets is used to search the solution of the problem. Finally,taking SWATH-6A as an example,the installed position,span and chord of stabilizer fins are optimized. According to the simulation result,the stabilizer fins which are got by optimization can make the SWATH work with the better longitudinal motion performance. Therefore,the established optimization method in this paper is reasonable and effective and is applicable.
