摘　　要：在货台空投稳降阶段,降落伞系统的摆动及着陆区域不平整地形等不确定因素不仅对气囊缓冲能力产生影响,严重时甚至可能导致货台侧翻,有必要针对这种更为一般的着陆条件进行仿真分析。在现有的空投系统气囊缓冲过程仿真模型基础上,考虑货台下落姿势和地面坡度两个因素,构建不确定因素下气囊缓冲的仿真模型,通过蒙特卡洛仿真获取大量结果样本点,结合置信水平得到货台着陆可靠度。算例结果表明,所建模型能有效模拟缓冲气囊的实际工作特性,仿真算法结果合理,可行性高,具有更广泛的工程应用价值。During the landing stage,uncertain factors such as the swing of the parachute system and the uneven terrain of the landing area not only affect the cushion capacity of the airbag,but may even cause the cargo platform to roll over in serious cases.It is necessary to conduct a simulation analysis for these more general landing conditions.Based on the existing airdrop system airbag cushion simulation model,considering the two factors of landing attitude and ground slope,a simulation model of airbag cushion under uncertain factors was constructed.A large number of sample points were obtained by Monte Carlo simulation.The landing reliability of the cargo platform was obtained combined with a confidence level.The example results show that the model can effectively simulate the actual working characteristics of cushion airbags.The simulation algorithm results are reasonable and high feasibility and have a wider application value in engineering.
