摘要
基于Johnson-Euler公式建立了中长柱整体加筋壁板压缩强度工程计算方法,经过7050铝合金整体加筋壁板的轴向压缩试验验证是合理的,压缩失稳载荷计算误差满足设计要求。在整体加筋壁板总面积相同的条件下,压缩失稳载荷随蒙皮与长桁的面积比λ增加呈现出先增加后降低的变化规律,据此通过调整λ可获得整体加筋壁板较佳的设计方案。
The whole stiffened panels of medium-length column compressive strength engineering algorithms are established based on the Johnson-Euler formula. The axial compression test of the whole stiffened panels with 7050 aluminum alloy is verified to be reasonable. The compression collapsing load calculation error meets the design requirements. With the same whole stiffened panel area, the compression collapsing load first in- creases and then decreases with increasing ratio of the skins and stringers area λ. Better design can he obtained by adjusting the λ of the whole stiffened panels.
