摘　　要：现有空投装备的气囊缓冲系统适用性较差,难以满足未来低冲击、抗侧翻的大吨位装备空投缓冲需求。针对这些问题,文章设计了可适用于新一代空投装备的组合式气囊,并采用最优拉丁超立方设计试验方法进行抽样,基于这些样本构建了以最大过载和最大翻转角为目标的多项式代理模型。在代理模型的基础上采用多目标粒子群优化算法对气囊的结构参数进行多目标优化,并对优化后的缓冲系统进行有限元分析,结果显示:优化后的气囊缓冲系统最大过载减少了24.7%,缓冲性能提高;最大横向翻转角降低了42.6%,其横向稳定性大幅度提高,大大降低了侧翻风险。研究结果表明,文章所设计并优化的气囊缓冲系统满足未来大载重、抗侧翻的需求,能够为空投装备气囊缓冲系统提供技术支持。The existing airbag buffer system of airdrop equipment is poor in applicability,and it is difficult to meet the future demand of airdrop buffer of large weight equipment with low impact and anti-rollover.To solve these problems,this paper designs a combined airbag suitable for a new generation of airdrop equipment,adopts the optimal Latin hypercube design test method for sampling,and constructs a polynomial proxy model aiming at maximum overload and maximum rollover angle based on these samples.The multi-objective particle swarm optimization algorithm is applied to optimize the structural parameters of the airbag on the basis of the agent model,and the optimized cushioning system is subjected to finite element analysis:the maximal overload of the optimized airbag cushioning system is reduced by 24.7%,which improves the buffer performance;the maximal rollover angle is reduced by 42.6%,which greatly improves the lateral stability,and greatly reduces the risk of rollover.The research results show that the airbag cushioning system designed and optimised in this paper meets the future demand of large load and rollover resistance,and provides technical support for the airbag cushioning system of future airdrop equipment.
