采用解析分析法,根据排气口流量方程和载荷运动方程建立了无量纲的空投设备气囊缓冲过程数学模型,并根据此模型构造了气囊的匹配设计图。讨论了排气口面积、气囊高度、着陆初速度、载荷质量、气囊底面积及排气口开启压力等参数对气囊缓冲性能的影响,提出了空投设备气囊缓冲系统的参数匹配设计方法,为空投设备气囊缓冲系统的匹配设计提供了技术支持。 Based on the analysis of discharge flow equation and load equation of motion, a mathematic model of the airbag cushioning process for dimensionless airdrop equipment was established by analyticanalysis, and the matching design of the airbag was constructed according to this model. The influence of parameters such as area of ​​exhaust port, height of airbag, initial landing velocity, mass of load, bottom area of ​​airbag and opening pressure of exhaust port on cushioning performance of airbag was discussed. A parametric matching design method of airbag cushioning system was proposed. Device airbag cushioning system matching design provides technical support.
