针对TiBw/TA15耐高温钛基复合材料加筋壁板，建立了其有限元数值模型，并进行了试验验证，使用特征值屈曲分析和弧长法研究了超塑成形/扩散连接(SPF/DB)加筋壁板在高温轴压环境下的屈曲模态、载荷以及后屈曲行为。结果表明，随着筋条宽度和筋条数量的变化，结构呈现出蒙皮局部屈曲、蒙皮整体屈曲以及结构整体屈曲3种不同的屈曲模式。随着温度的升高，不同屈曲模态对应的屈曲载荷Fcr均下降较为明显。使用钛基复合材料加筋壁板结构的屈曲载荷Fcr和破坏载荷Fp均显著高于TC4钛合金。
Abstract：The finite element numerical model of TiBw/TA15 high-temperature resistant titanium matrix composite stiffened panel was established and test verification was carried out. Eigenvalue buckling analysis and arc length method were used to study the buckling mode, load and post-buckling behavior of superplastic forming/diffusion bonding(SPF/DB)stiffened panel under high-temperature axial pressure condition. The results show that as the width and number of stiffeners change, the structure presents three different buckling modes, which are local buckling of skin, whole buckling of skin and whole buckling of structure. With the increase of temperature, the bulkling load Fcr corresponding to different buckling modes decreases significantly. The bulkling load Fcr and the failure load Fp of the structure using titanium matrix composite stiffened panels are significantly higher than that of TC4 titanium alloy.
