摘要
为确定某型飞机平尾壁板结构截面尺寸参数,验证计算分析方法是否合理、有效,通过有限元屈曲分析与试验相结合的手段,对复合材料加筋壁板轴压稳定性进行研究。研究了复合材料加筋壁板在相同支持条件下,提高加筋壁板筋条截面积占总截面积的比例对复合材料加筋壁板初始屈曲和承载能力的影响。试验结果表明:试验结果与计算结果较为接近,说明计算中采用的分析方法和分析模型准确有效;在筋条截面积比例提高3.0%的情况下,屈曲载荷提高10.0%左右。所得结论可指导复合材料加筋壁板设计在型号研制中的应用,为初步确定平尾壁板结构截面形式和尺寸提供参考。
In order to determine cross-section size parameters of the horizontal stabilizer plane of a certain aircraft, and validate that the simulation analysis method is reasonable and effective,axial compression stability of composite stiffened panel was studied by finite element buckling analysis and tests.Under the condition of the same support,it was researched that the tendency of the initial buckling and bearing capacity for composite stiffened panel caused by increasing the ratio of stringer cross-section area occupied the whole cross-section area.Test results show that test results and calculation results are consistent,which prove that the analysis method and analysis model are accurate and effective.The buckling loads would increase about 10.0% with the ratio of stringer cross-section area increasing 3.0%.This result would be used to guide the composite stiffened panel design work in aircraft type development, and provide reference for whose preliminary determination of the types and parameters of cross-section for horizontal stabilizer plane.
