摘　　要：以复合材料力学经典层合板理论为基础,利用MATLAB编程联合ANSYS有限元分析,建立了复合材料声呐导流罩铺层结构优化平台。首先对单向载荷下的层合板铺层结构进行优化,并和实验结果相比较,验证了该优化平台的有效性。结果表明,优化后的层合板强度有了较大提高。在此基础之上,根据水下实际载荷工况,对声呐导流罩的铺层进行了优化设计,并利用ANSYS有限元分析对优化后的铺层进行应力应变分析。结果表明,声呐导流罩强度性能显著提高,实现了声呐导流罩铺层的优化设计。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.
