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。

By analytical method,according to the vent flow equation and load motion equation,a non-di-mensional mathematical model of airbag cushioning is established,and accordingly airbag matching de-sign charts are drawn.Based on the model,the effect of vent area,height and bottom area,initial veloci-ty,load mass and the pressure of vent opening on airbag buffer properties are analyzed,and a set of air-bag parameter matching design method is established.This method can provide technical support for the matching design for airbag cushioning system of airdropped equipment.
