The invention provides a load shedding method and device for high-speed parachute opening of a human parachute, a parachute rope of the human parachute is connected with a connecting belt through a buffer energy absorption connecting device for absorbing kinetic energy transmitted when the human parachute is opened, the buffer energy absorption connecting device comprises a support and an elastic energy absorption mechanism, and the support is a closed rod piece composed of a U-shaped rod and a fixed rod. The elastic energy absorption mechanism comprises a lifting rod, an elastic piece and a guide rod, sliding grooves are formed in the two ends of the lifting rod and matched with the two side edges of the fixing rod, a guide column is arranged on the bottom face of the lifting rod, the guide column is sleeved with the elastic piece, the end of the guide column penetrates through a through hole in the fixing rod, and the two ends of the elastic piece abut against the lifting rod and the fixing rod respectively. Kinetic energy transmitted when a person opens the parachute can be absorbed, loads acting on passengers are reduced, and injuries to the passengers are reduced.
本发明提出一种人用降落伞高速开伞的减载方法和装置,人用降落伞的伞绳与连接带通过缓冲吸能连接装置相连,用于吸收人用降落伞开伞时传递的动能,缓冲吸能连接装置包括支架和弹性吸能机构,支架由U型杆和固定杆组成闭合杆件,弹性吸能机构包括升降杆、弹性件和导向杆,升降杆的两端设有滑槽与固定杆的两侧边相配置,升降杆底面上设有导向柱,弹性件外套于导向柱,导向柱端头穿过固定杆上的通孔,弹性件两端头分别与升降杆和固定杆相抵接。本发明能吸收人用降落伞开伞时传递的动能,使作用在乘员上的载荷得到降低,减轻对乘员的损伤。
