【摘要】：為確定某型飛機(jī)平尾壁板結(jié)構(gòu)截面尺寸參數(shù),驗證計算分析方法是否合理、有效,通過有限元屈曲分析與試驗相結(jié)合的手段,對復(fù)合材料加筋壁板軸壓穩(wěn)定性進(jìn)行研究。研究了復(fù)合材料加筋壁板在相同支持條件下,提高加筋壁板筋條截面積占總截面積的比例對復(fù)合材料加筋壁板初始屈曲和承載能力的影響。試驗結(jié)果表明:試驗結(jié)果與計算結(jié)果較為接近,說明計算中采用的分析方法和分析模型準(zhǔn)確有效;在筋條截面積比例提高3.0%的情況下,屈曲載荷提高10.0%左右。所得結(jié)論可指導(dǎo)復(fù)合材料加筋壁板設(shè)計在型號研制中的應(yīng)用,為初步確定平尾壁板結(jié)構(gòu)截面形式和尺寸提供參考。
[Abstract]:In order to determine the cross-section dimension parameters of a plane flat-tailed panel structure and verify whether the calculation and analysis method is reasonable and effective, the axial compression stability of composite stiffened panel is studied by means of the combination of finite element buckling analysis and test. The effect of increasing the ratio of reinforced slabs to total cross-sectional area on the initial buckling and bearing capacity of reinforced composite slabs under the same supporting conditions was studied. The experimental results show that the experimental results are close to the calculated results, which shows that the analytical method and the analytical model used in the calculation are accurate and effective, and the buckling load is increased by about 10.0% when the ratio of section area of steel bars is increased by 3.0%. The conclusions can be used to guide the design of reinforced composite panels in the development of the model and provide a reference for the preliminary determination of the cross-section form and size of the flat-tailed panels.
