摘要
根据CSR高级屈曲分析方法,运用有限元软件ABAQUS,研究削斜筋板架的屈曲能力,计算了5筋板架、小削斜筋板架、削斜筋板架以及4筋板架的屈服强度以及极限强度。结果表明:加强筋削斜后,加筋板屈服强度的下降比极限强度更明显;在纵向载荷条件下,承载能力随着加强筋的削斜而降低,而在横向载荷条件下,其极限强度没有明显下降。
According to the CSR senior buckling analysis method, this paper studies the buckling capacity of the snip stiffened panel through the ifnite element software ABAQUS. It calculates the yield strength and the ultimate strength of the ifve-stiffened plate, the small snip stiffened plate, the snip stiffened plate and the four-stiffened plate. The results show that the yield strength of the stiffened plate with the snip stiffener decreases more obviously than its ultimate strength. Under the condition of the longitudinal load, carrying the capacity declines with the snip stiffener, while under the condition of the lateral load, the ultimate strength doesn＆#39;t show any obvious decrease.
