摘要 对被粘接件为钢板和铝板的刚度平衡、非平衡搭接胶接接头进行不同温度下的拉伸载荷剪切强度试验,分别得到各种类型搭接件在3种温度下的最大拉伸力值。以Goland和Reissner的一维梁模型为基础,参考Wu Z J提出的接头解析方法推导出求解刚度不平衡接头端部载荷的相关公式,并且通过有限元仿真对试验中各种类型接头进行胶层应力分析,最后针对刚度非平衡结构对接头强度的影响进行了讨论。 In order to explore the strength of the structures with unsymmetric lap-joints,the adhesively bonded single-lap joints whose adherends were steel sheets,aluminum sheets and steel-aluminum were separately tested in tension loading which created shear across the bondline.The tests were conducted under different temperatures to provide the experimental tension loads for the three kinds of dissimilar lap-joints.According to the method which Wu Z J proposed,the equations of edge-loads were given based on G-R's theory.The stress of adhesive was obtained through finite element analysis.In addition,the effects of the unsymmetric structure on the strength of joints were discussed.
