The invention provides an airplane passenger cabin floor stand column used for supporting a passenger cabin floor of a large civil airplane, and belongs to the technical field of anti-collision energy absorption structure manufacturing. The airplane passenger cabin floor stand column is an I-shaped stand column with an I-shaped cross section and comprises a web plate and flanges symmetrically arranged on the two sides of the web plate. The web is parallel to the length direction of the flanges; the upper end of the I-shaped stand column is an upper connecting section, and the lower end of the I-shaped stand column is a lower connecting section. The part, located between the upper connecting section and the lower connecting section, of the I-shaped stand column is an energy absorption section. And the energy absorption section is provided with a cutting design. The web and the flange of the energy absorption section of the I-shaped stand column are cut and designed in different forms, the I-shaped stand column is more easily guided to gradually deform step by step under the crushing load, it is guaranteed that the stand column structure gradually deforms step by step and absorbs large falling and collision energy, meanwhile, the structure weight can be reduced to the maximum extent, and the structure cost is reduced. And the use of aviation fuel is reduced.

    本发明提供了一种飞机客舱地板立柱,用于支撑大型民用飞机客舱地板,属于防撞吸能结构制造技术领域。所述飞机客舱地板立柱为横截面形状为工字型的工字型立柱,其包括:腹板和对称设置在腹板两侧的翼缘;所述腹板和翼缘的长度方向平行;所述工字型立柱的上端为上连接段,下端为下连接段;所述工字型立柱上位于上连接段、下连接段之间的部分为能量吸收段;在所述能量吸收段上有裁剪设计。本发明对工字型立柱的能量吸收段的腹板和翼缘进行不同形式的裁剪设计,更易引导工字型立柱在压溃载荷下逐级发生渐进变形,并在保证立柱结构发生逐级渐进变形、吸收较大坠撞能量的同时,能够最大限度减少结构重量,减少航空燃油的使用。
