摘要
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.
Based on the dynamic simulation on cargo airdropping systems in landing and cushioning processes, the sensitivity analysis on peak-value acceleration impact factors, including five cargo state factors such as the vertical landing velocity, horizontally-longitudinal velocity, horizontally-transverse velocity, cargo longitudinal postural angle and cargo transverse postural angle, is conducted using the orthogonal experiment design and statistical analysis methods. Therefore, it is found form testing results that the factors from the vertical landing velocity, rather than the horizontal landing and landing posture, significantly impact peak acceleration values.
