为了深入理解次加筋板的稳定性能,应用ABAQUS对等质量的3种典型的次加筋板结构形式进行了线性屈曲和非线性后屈曲性能计算,并将结果与传统加筋板的稳定性能进行对比。结果表明,次加筋板相对与传统加筋板稳定性有很大提高。在仅考虑线性屈曲性能时,对其中稳定性性能最好的棱柱形次加筋板的长宽比、次筋条条数和高度3个参数进行了参数分析,发现长宽比在一定范围内的棱柱形次加筋板才具有应用价值,且它存在最优的次筋条高度,使得棱柱形次加筋板的稳定性最好,这对棱柱形次加筋板的理论分析和工程应用具有一定的参考价值。
In order to understand the stability of sub-stiffened panels, linear buckling and non-linear buckling performance of three typical sub-stiffened panels with ABAQUS equivalent quality were calculated. The results were compared with those of traditional stiffened panels comparing. The results show that the relative stiffener plate has a great improvement on the stability of the traditional stiffened plate. When only the linear buckling performance is considered, the parameters of the length-width ratio, the number of secondary ribs and height of the prismatic secondary stiffened plate with the best stability are analyzed. It is found that the aspect ratio is within a certain range Of the prismatic sub-stiffener has its application value, and it has the best sub-stiffener height, making the prismatic sub-stiffened plate the best stability, the prism-shaped stiffened plate theoretical analysis and engineering applications Has a certain reference value.
