摘要



摘 要:本文建立了载人着陆冲击的“假人-座椅”数值模型,并进行了数值模拟和实验验证。模型经验证后,其数值结果与实验数据非常接近,并基于Sobol法对人体不同部位角度对人体头-颈部损伤响应的影响进行了灵敏度分析。结果表明:人体头-颈部角度和体位角对人体损伤响应有着重要影响。根据分析结果,可为最佳人体着陆姿势的研究提供变量选取依据,在载人空降防护技术领域具有一定的实际工程意义。






Abstract

Abstract: The “dummy-seat” numerical model was constructed and the results of numerical simulation were approached to the experiment. The sensitivity values of body parts angle were calculated based on the Sobol method. The results demonstrate that the head-neck angle and body angle have influence on human injury responses. According to the analysis results, the engineers could research the optimal astronaut landing position. The method can also be used in the field of other airdrop protections.
