The invention discloses a working method of a rigid-flexible coupling airborne loading combined buffer device. The device comprises an airborne material storage box, a buffer spring, an inner buffer air bag, an inner spherical shell, an outer buffer air bag and an outer spherical shell. In the loading airborne landing process, the outer spherical shell deforms firstly, and first-stage buffering isachieved; then a folding buffer connecting piece deforms, and second-stage buffering is achieved; the outer buffering air bag is compressed, and the outer buffering air bag exhausts air and relievespressure outwards through an outer buffering air bag exhaust valve so that three-stage buffering is realized; the inner spherical shell is deformed after being subjected to a load so that four-stage buffering is realized; the buffer spring contracts subsequently to realize five-stage buffering; the inner buffer air bag is finally compressed and the inner buffer air bag exhausts air and relieves pressure outwards through the inner buffering exhaust valve, and six-stage buffering is achieved; by means of the multi-stage buffering method of the airborne landing device, impact energy can be absorbed stage by stage, the internal pressure of the buffering air bag can be prevented from being sharply increased, the buffering air bag is prevented from blasting, and therefore, the integrity of materials in the airborne landing device is effectively guaranteed.
本发明公开了一种刚柔耦合的空降载物联合缓冲装置的工作方法,所述装置包括空降物资储存箱、缓冲弹簧、内缓冲气囊、内球壳、外缓冲气囊和外球壳;载物空降着陆过程中,外球壳首先发生变形,实现一级缓冲;随后折叠缓冲连接件发生变形,实现二级缓冲;外缓冲气囊后被压缩,并通过外缓冲气囊排气阀向外排气泄压,实现三级缓冲;内球壳后受到载荷发生变形,实现四级缓冲;缓冲弹簧随后收缩,实现五级缓冲;内缓冲气囊最后被压缩,并通过内缓冲排气阀向外排气泄压,实现六级缓冲;通过空降装置的多级缓冲方法不但能够实现逐级吸收冲击能量,还能避免缓冲气囊的内部压力急剧增加,防止缓冲气囊爆破,从而有效保证空降装置内物资的完好性。
