结合货台空投系统着陆缓冲过程动态模拟,采用正交试验设计方法及其统计分析方法,进行货台的5个状态因素(垂直着陆速度、水平纵向速度、水平横向速度、货台纵向姿态角以及货台横向姿态角)及其交互作用对货台着陆峰值加速度影响的灵敏度分析.试验结果表明,垂直着陆速度是峰值加速度最主要的影响因素,水平速度和着陆姿态的影响不显著.
Combining with the dynamic simulation of the landing buffer process of the cargo drop airdrop system, the orthogonal test design method and its statistical analysis method were used to analyze the five state factors (vertical landing speed, horizontal longitudinal speed, horizontal transverse speed, longitudinal attitude angle of the cargo platform and The sensitivity analysis of the impact of the interaction between the landing acceleration and the peak acceleration of the cargo platform is shown in the experimental results. The results show that the vertical landing velocity is the most important factor of peak acceleration, and the horizontal velocity and landing attitude are not significant.
