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。
Aiming at the safety protection of manned airborne occupants, a new airbag cushion seat and bionic airbag neck are designed based on airbag cushioning principle, and the airborne occupant is more effectively protected in all aspects. The numerical simulation of airbag cushioning device was carried out by carrying out the equipment landing crash test and the dynamic characteristics parameters of the airbag device were optimized by micro-multi-objective genetic algorithm. The results show that the method not only can reduce the number of airborne tests and the cost of expensive test, Can provide a variety of programs for engineering staff to meet different product requirements, manned airborne protection technology has some practical engineering significance.
