摘　　要：为研究一种快速获得蜂窝夹层结构抗鸟撞冲击响应的失效参数反演的方法,建立显式非线性鸟撞有限元模型,利用试验设计方法克服人工试凑法的局限性,并在响应面基础上对变形量进行了优化。研究表明失效模型参数中的塑性功对结构破坏有比较大的影响。进行了真实物理验证试验,对比结果表明了方法的准确性,仿真精度有所提高。To study a kind of method that could quickly get the honeycomb sandwich structure failure model parameters of the shock response of strike of bird,nonlinear finite element model was established in this paper,and based on the response surface,the deformation were optimized. Experiment design method overcame the limitations of artificial trial and error was used to study results show that the maximum plastic work have large influence on structure damage. Physical verification test showed that the accuracy of the inversion method and the simulation precision was improved.
