摘要: 针对载人空降乘员安全防护问题,基于气囊缓冲原理设计一种全新的气囊缓冲座椅和仿生气囊护颈,更有效地对空降乘员实施全方位的保护。通过开展装备落地碰撞试验对气囊缓冲装置的数值模型进行校正,并运用微型多目标遗传算法对气囊装置的动态特性参数进行优化,结果表明该方法不但能减少空降试验次数与昂贵试验成本,而且还能为工程人员提供多种方案以满足不同产品要求,在载人空降防护技术领域具有一定的实际工程意义。

Abstract: In order to improve ability of manned airdrop protection, the airbag-chair and neck protection device are designed to ensure the safety of passengers. The numerical model of airbag is validated by the vehicle airdrop experiments and the micro multi-objective genetic algorithm with high efficiency is adapted to searching the key parameters of the airbag dynamic characteristic. The optimization results demonstrate that the proposed method not only gives optimal design of airbag protection devices with reducing experiment times and cutting down experiment cost , but also the several dynamic characteristic of airbag which could fulfill different needs are acquired. The method can also be used in the field of other airdrop protections.
