| 摘 要： | 针对物资在空投过程中有(无)某新型空投用缓冲装置和有(无)着陆倾斜角的四种不同撞击土壤情况,对该装置落地时缓冲板的缓冲系数和缓冲能量建立了非线性回归模型,并将其与地锚、缓冲气囊的缓冲效果进行叠加,最后分别运用动静法分别求解出有(无)缓冲装置时的空投物资落地冲击力并对之进行了对比,为该装置的设计优化提供了理论依据。经计算可知:空投用缓冲装置可以有效降低空投时的冲击力;装置的缓冲效果会随着空投物资质量的增加而下降。

| Abstract: | Specific to four different cases in which a new airdrop buffer hits the ground with or without a buffer,and with or without any inclination angle in the process of airdrop,a nonlinear regression model is built for cushion coefficient and the cushion capacity of the buffer plate during its falling to the ground.Then the model is superimposed with the buffering effect of the anchor and the airbag.Lastly,the impact forces of landing cargo with/without a buffering mechanism are calculated and compared,which pro... |
