摘要

摘要: 由于复合材料板架结构具有各向异性、界面复杂及可设计变量众多等特性,因而在开展优化设计时往往困难重重。对此,采用分级递进优化设计方法。以某型舰甲板室舷侧复合材料夹层板架结构为对象,首先根据工程实际并结合复合材料板架结构的设计特点,提取所有可设计变量,并在此基础上分析所有设计变量的灵敏度特征规律；然后,对该夹层板架结构进行两级优化计算与分析；最后,对优化前后的计算结果进行对比分析。研究结果表明,分级递进优化设计方法能有效解决复杂的复合材料板架结构多变量设计问题。

Abstract: The optimization design of composite stiffened panel can be difficult to carry out due to its innate features such as anisotropy,complex interfaces and multivariate design etc. In this paper,a hierarchical progressive optimum design method is proposed,where the side composite stiffened panel of superstructure is selected as the research object. Firstly,all available design variables are extracted according to actual engineering practices and the design characteristics of composite stiffened panels. Then,calculation and analysis for the two-stage optimization are conducted on the stiffened panel by investigating the sensitivity of all design variables. Finally,a comparison of results before and after the optimization shows that the hierarchical progressive optimum design method effectively solves the multivariate design problems of complex composite stiffened structures.
