摘　　要：为有效提高结构设计效率,采用分级优化策略,针对某型号运载火箭整流罩壳段铆接舱体的结构参数开展优化设计研究。首先,基于Isight优化平台,调用Abaqus软件计算结构的屈曲承载能力,采用串行优化的方式,通过试验设计方法分析确定主要结构参数;其次,使用HookeJeeves无约束优化方法进行结构参数分析。通过两轮优化依次确定主结构的设计参数及结构布置方案,使铆接舱体结构在满足轴压承载能力的情况下质量最轻。通过数据分析,发现优化后的结构质量降低了24.6%,在提高结构承载效率的同时,给出的符合工程实际需求的结构设计方案可有效降低商业航天器的发射成本。To effectively improve the efficiency of structure design,a hierarchical optimization strategy was adopted to conduct optimization design on the structural parameters for the riveted cabin section of a certain type of carrier rocket fairing shell.Firstly,with the Isight optimization platform,and the Abaqus software was called to calculate the buckling bearing capacity of the structure.A serial optimization approach was used to analyze and determine the main structure parameters using experimental design methods.Secondly,the Hooke-Jeeves unconstrained optimization method was adopted for structural parameter analysis.Through two rounds of optimization,the design parameters and structural layout scheme of the main structure were determined in sequence,then the riveted cabin structure had the lightest weight and could meet the axial compression bearing capacity.Through data analysis,it was found that the optimized structural quality decreased by 24.6%.With improving the structure loadbearing efficiency,a structural design scheme that could meet the actual engineering requirements was provided,which can effectively reduce the launch cost of commercial spacecraft.
