摘要
Abstract
The ifnite element modeling method of using auxiliary laminate and adding negligible material with inifnitesimal elastic module on the skin and the lower lfange of stringer, as well as the parametric modeling function of PATRAN/NASTRAN and genetic algorithm were applied to optimize 5 different composite stiffened panels under certain constraints and compression load from 2000 N/mm to 6000 N/mm. It was found that the most efifcient composite stiffened panel is J section from 2000 N/mm to 4500 N/mm, and I-stiffened panel is the optimum conifguration when the compression load is greater than 4500 N/mm.关键词
