摘要 对压印接头进行了拉伸-剪切试验,用有限元软件对压印接头的拉剪过程和失效模式进行有限元模拟,并推导出了拉剪强度的预测公式。结果表明:根据压印接头的截面形状和尺寸,并充分考虑材料之间的接触形式和摩擦而建立的有限元模型,能够较好地预测压印接头的拉剪强度和失效模式;铝-铝和钢-钢同种材料的压印接头在拉剪载荷下的失效模式为上板在颈部最薄处断裂;提出的压印接头强度预测公式能准确预测接头强度,铝-铝接头和钢-钢接头拉剪强度的预测误差分别为4.6%和5.8%;拉剪强度主要取决于连接模具半径、上板材料强度和颈部厚度。 Tensile-shear test was carried out for clinched joint, and finite element model was establishes to simulate the tensile shear process and the failure mode, and lap shear strength prediction formula was presented. The results show finite element model, which was established by shape, size of section of clinched joint and considering the contact conditions and friction between materials and friction, could be used to predict the lap shear strength and failure mode of clinched joint. Failure occured in the upper sheet with the minimum thickness for AI-A1 and steel-steel clinched joints in the tensile-shear tests. Strength formula for joint strength could be used to predict the lap shear strength of clinched joint with the error of 4. 6~ for A1 A1 clinched joint and 5.80/oo for steel-steel clinched joint. The lap shear strength mainly depended on the punch radius, shear strength of upper sheet and the neck-thickness.
