空投装备着陆冲击环境适应性研究

摘要

Objective To study the landing environmental worthiness of airborne equipment. Methods Based on finite element method, response surface and Monte Carlo method, the successful landing probability was predicted. The influence of different landing velocity, land surface slope and surface wind on the successful landing probability was studied. The landing environmental worthiness data of airborne equipment was analyzed, and the measures for improving landing environ-mental worthiness of airborne equipment were proposed. Results The results proved that vertical velocity and surface wind had significant influences on the probability of success, while the surface slope had insignificant influence. Conclusion The successful landing probability could be predicted based on the research on landing environmental worthiness. The results could provide theoretical reference and technical guidance for airdrop.%目的：研究空投着陆冲击环境适应性。方法采用有限元、响应面和蒙特卡罗方法，预测空投着陆成功概率；研究不同垂直着陆速度、地面坡度和地面风速对空投着陆成功概率的影响；分析空投装备着陆冲击环境适应性数据，提出提高空投装备着陆冲击环境适应性的措施。结果垂直速度和地面风速对综合成功概率影响显著，地面坡度的变化对综合成功概率的影响不显著。结论通过该方法，能够成功预测空投着陆成功概率，为空投实践提供理论依据和技术指导。
