摘要： 针对铝镁合金单搭接胶接接头,建立了剪滞解析模型,得到接头剪切应力的一般分析方法,利用有限元模型验证了该方法的有效性。在三维弹塑性有限元模型的基础上,分析了铝镁合金单搭接胶接接头剪切应力、Von-Mises等效应力在胶层厚度、宽度方向上的分布规律,结合试验探讨了胶粘剂类型、胶层厚度、胶接搭接长度对胶接结构连接强度的影响。所得结果对胶接工艺金属材料与胶层属性匹配、接头强度预测及胶接接头性能优化具有指导意义。

Abstract: A shear-lag analytical model for aluminum-magnesium alloy single-lap joints was established to predict the joint shear stress. The predicted distribution of shear stress was verified using finite element model. Based on the three dimensional elastic-plastic finite element model, the distributions of shear stress and Von-Mises equivalent stress of the alloy joints in the adhesive layer thickness- and width-direction are analyzed. The effects of various parameters, such as adhesive type, layer thickness and adhesive length, on the bonded structure strength are discussed with experiment and simulation. The results of this study may provide guidance for matching different kinds of metals and adhesives and are helpful in strength prediction and performance optimization of adhesive joints.

Key words: vehicle engineering, aluminum alloy, magnesium alloy, adhesive bonding, single-lap joints, shear-lag analytical model, stress distribution, strength prediction
