建立了飞机机翼壁板热压罐时效成形的数学模型。以梁试件时效成形为例说明了建模过程。结果发现，一个封闭的形式的解决方案，可以得到一个模具的形状为圆弧。封闭形式的解决方案是不可能的其他模具形状和数值方法，因此，开发和应用到两个非圆形模具形状。预测结果与德事隆航空结构公司获得的实验数据进行了比较，结果吻合良好。
A mathematical model of autoclave age forming of aircraft wing panels is developed. The modeling process is illustrated by application to age forming of beam specimens. It is found that a closed form solution can be obtained for a mold in the shape of a circular arc. Closed form solutions are not possible for other mold shapes and a numerical method is, therefore, developed and applied to two noncircular mold shapes. Comparisons of predictions with experimental data obtained by Textron Aerostructures yield good agreement.
