THE OPTIMIZATION OF COMPOSITE LAMINATES FORSONAR DOME BY GENETIC ALGORITHM

Abstract

Abstract: In this paper, based on the Classical Laminate Theory of composite mechanics, an optimization platform of composite laminate design by Matlab and Ansys were developed for sonar dome. The optimization platform is verified by considering a laminate under uniaxialloading, with the optimization results compared with experiments.The results show that the strength of the laminates improves as the optimization progresses, and the optimum design gives greatly improved strength, and good agreement is achieved between the numerical and experimental results. Thereafter, the laminate of the sonar domeare is optimized according to the actual underwater load conditions. The stress and strain fields of the optimized laminate are obtained by ANSYS. It is shown that the strength and stiffness of the sonar dome has been significantly improved, and the optimization of the sonar dome laminate is fulfilled successfully.

Key words: composite laminate, sonar dome, design optimization, genetic algorith
