Traditional CAE modeling of door structures typically employs uniform wall thickness properties, failing to account for thickness variations after sheet metal forming. Therefore, it is of practical significance to develop a structural CAE model that incorporates the non-uniform wall thickness resulting from the forming process of door inner and outer panels. This paper investigates a method for constructing a structural CAE model of aluminum alloy door panels with non-uniform thickness based on forming analysis. In this model, the wall thickness properties of the inner and outer panels are assigned the non-uniform thickness values obtained from formability CAE analysis. A comparative analysis is conducted between the calculated stiffness and experimental stiffness of the aluminum alloy door panels using both uniform and non-uniform wall thickness CAE models. The results show that, compared to the uniform thickness CAE model, the structural CAE model based on forming-induced non-uniform thickness significantly improves the accuracy of door stiffness predictions. Specifically, the accuracy of torsional stiffness calculations at the upper corner point increases by 10.6%, at the lower corner point by 6.3%, at the outer waistline by 5.2%, at the inner waistline by 5.5%, at the upper mounting point of the window regulator by 7.7%, and at the lower mounting point of the window regulator by 7.5%.

传统车门结构CAE建模采用等壁厚属性，未考虑板料成形后的壁厚变化，故建立车门内外板成形非均匀壁厚的结构CAE模型具有现实意义。研究了铝合金车门内外板成形非均匀壁厚的结构CAE模型构建方法，将结构CAE模型内外板壁厚属性赋予成形性CAE分析的非均匀壁厚数值，开展铝合金车门内外板等壁厚、非均匀壁厚CAE模型计算刚度与试验刚度的对比分析。基于成形非均匀壁厚的铝合金车门结构CAE分析模型与等壁厚CAE分析模型相比，车门刚度CAE计算结果精度明显提升，车门上角点、下角点扭转刚度计算结果精度分别提升10.6%、6.3%，车门外腰线、内腰线刚度计算结果精度分别提升5.2%、5.5%，车门玻璃升降器上安装点、下安装点刚度计算结果精度分别提升7.7%、7.5%。
