从复合材料定向管的动态特征研究出发，以铺层厚度h和铺层角θ为优化设计变量，基于Tsai－Wu失效准则，在满足强度要求的条件下，以质量最轻为优化目标，运用多岛遗传算法与序列二次规划法相结合的优化策略，基于iSIGHT优化平台建立了定向管的动力学优化求解框架，获得了具有优异综合性能的复合材料定向管的设计方案。结果表明，优化后的复合材料定向管质量减轻了24％。

The dynamic characteristics of composite directional tube were researched.The layer thickness h and the ply angleθwere taken as the variable of optimization design.Based on the Tsai-Wu failure criterion, the minimum mass was taken as the goal of optimization under the condition that strength meets the requirement;the optimization strategy was obtained when the Multi-island Genetic Algorithm was combined with the Sequential Quadratic Programming.The dynamics optimization solution frame-work of directional tube was established based on the optimization platform iSIGHT.And the design scheme was got for the com-posite directional tube with excellent and comprehensive performance.The results show that the mass of the directional composite tube reduced 24%after optimization.
