According to the aircraft cargo hold arresting net structure and the design method. The arresting net is arranged at the front position of an aircraft cargo hold and connected with the wall of the aircraft cargo hold, the arresting net comprises a flexible bag net, and the two sides of the flexible bag net are hinged to a reinforcing frame of the aircraft cargo hold through a plurality of rigid force bearing belts respectively. The rigid force bearing belt converts most of arresting loads into course loads with high load bearing capacity of the aircraft and transmits the course loads to the bulkhead of the aircraft body, so that the opposite-pull loads borne by the aircraft in the frame plane are greatly reduced. Meanwhile, the flexible bag net of the arresting net is a square net with the consistent net belt length, the deformation amount of the arresting net during bearing is equivalent, the load value transmitted to the fuselage connecting structure is basically equivalent, and the reinforcing design of the fuselage connecting structure is facilitated.
一种飞机货舱拦阻网结构及设计方法,该拦阻网设置在飞机货舱的前部位置,与飞机货舱壁连接,所述的拦阻网含有柔性兜网,该柔性兜网的两侧通过多个刚性承力带分别铰接在飞机货舱的加强框上。刚性承力带将大部分的拦阻载荷转化为飞机承受载荷能力较强的航向载荷传递给机身舱壁,使飞机所受的框平面内的对拉载荷大幅度降低。同时由于本申请的拦阻网的柔性兜网是一个网带长度一致的方形网,拦阻网在承载时变形量相当,其传给机身连接结构的载荷量值也基本相当,便于机身连接结构的加强设计。
