摘　　要：采用内聚力模型,对铝板环氧树脂胶接接头进行强度分析,模拟胶层加载过程中胶层单元失效扩展,并进行胶接接头力学实验与仿真结果对比,证明此方法的有效性;并将此方法运用于预测某复杂结构铝管胶接接头强度,为工程上合理选择胶接材料和快速估算胶接接头的承载能力提供了参考。On the basis of cohesive zone model, strength analysis is used to simulate dynamic failure propagation of cohesive element in adhesive bonded joints of aluminium in the loading progress. Then it＇s proved to be in effect by comparing simulation result with the corresponding mechanical experiment. This method is succeed in predicting a complex structure＇s joint strength of aluminium, which provides with available reference in selecting reasonable pastern materials and quickly evaluating loading ability of adhesive bonded joints.
