分别采用库仑摩擦模型、剪切摩擦模型和混合摩擦模型，采用板法和有限元方法对局部加载成形过程进行了分析。结果表明，剪切摩擦模型和混合摩擦模型的预测结果基本一致，但库仑摩擦模型与其他两种摩擦模型的预测结果存在显著差异。库仑摩擦模型能较好地填充肋腔，且随着局部载荷宽度的增加，库仑摩擦模型和剪切摩擦模型成形后的肋高相差先增大后减小。
The Coulomb friction model, shear friction model and hybrid friction model were employed to analyze the local loading forming process by using slab method (SM) and finite element method (FEM). The results indicated that predicted results by shear friction model and hybrid friction model are almost the same, but there exists a notable difference between Coulomb friction and the other two friction models. The rib cavity will be filled better under Coulomb friction model, and difference of rib height after forming process between Coulomb friction model and shear friction model increases at first and then decreases with the increase in width of local loading.
