摘要

为研究设计最优环形柔性复合防护结构，建立环形柔性复合结构优化设计方案和有限元模型，开展数值仿真分析，得到了冲击波在环形柔性复合防护结构内的传播规律，并与试验进行对比，仿真计算结果与试验数据吻合良好。基于批量化数值仿真计算结果，进行优化设计，构建了关键设计参数的响应面模型并分析了其灵敏度，通过NSGA-II算法得到了最优防护结构，并开展对比实爆试验。研究结果表明：采用优化后的防护结构，能够具备重量轻、内径大、高度低、冲击波压力峰值低的特点，相对于未优化的重量减轻了9.1%，冲击波压力峰值降低了18.7%。

Abstract

To study and design the optimal circular flexible composite protective structure

an optimized design scheme andafinite element model for the circular flexible composite structurewereestablished.Numerical simulation analysiswas thenconducted toobtain the propagation law of shock waves in the structure

the simulation resultswerein good agreement with the experimental data.Based on the results of batch numerical simulations

optimization designwascarried out

response surface model for key parameterswasconstructed and its sensitivitywasanalyzed.Theoptimalprotective structurewasobtained through the NSGA-II algorithm

and comparative real explosion testswereconducted. The results show that the optimizedprotectivestructurefeatureslight weight

large inner diameter

low height

and low peak shock wave pressure. Compared withthe unoptimized structure

the weight is reduced by 9.1%andthepeakshock wavepressure is decreased by 18.7%.
