摘　　要：运用ABAQUS的二次开发语言对复合材料定向管进行参数化建模,通过火箭弹发射过程的瞬态动力学分析对复合材料定向管的铺层角度进行优化设计,以提高其结构强度。设计过程中利用优化软件iSIGHT集成有限元分析软件ABAQUS,采用多岛遗传算法和序列二次规划法相结合的优化算法,进行瞬态动力学的优化。经过优化设计,得到了合理的铺层角度,使复合材料定向管的强度性能有了显著提高。Parameterized model of the composite materials director was built with ABAQUS Python development environment, which made preparation for integrated optimization. With the transient dynamics analysis of the rocket launching process, the ply orientation angle of composite materials director was optimized to improve its structural strength. In the process of optimization design, the multi-island genetic algorithm and sequential quadratic programming synthetic optimization algorithm are combined for the transient dynamic optimization by the integration of the ABAQUS and the iSIGHT. After the optimization design, a reasonable ply orientation angle is obtained, which significantly improves the strength performance of the director.
