总结胶接接头的标准单元模拟方法,建立接头相应的有限元模型,将各种接头的有限元计算刚度与试验刚度进行对比分析。研究结果表明:弹簧单元模拟精度最高,但建模效率较低;实体单元建模效率较高,但模拟精度不及弹簧单元。该结论为胶接结构有限元分析提供一定的参考价值。
Abstract：Standard element simulation methods of adhesive joint were summarized. The corresponding finite element model of the joint was established,and finite element calculated stiffness and the experimental stiffness of various joints were compared. The research results showed that the simulation accuracy of spring element was the highest,but the modeling efficiency was low;the modeling efficiency of solid element was relatively high,but the simulation accuracy was lower than that of spring element. This conclusion provided the reference for finite element analysis of adhesive structure.
