摘　　要：胶接是碳纤维复合材料(CFRP)传动轴与其他部件连接的最主要方式。由于胶接强度的不确定性,应用有限元软件研究胶层设计的合理性已成为一种普遍选择。首先研究了胶接接头的失效准则、胶接接头刚度平衡设计准则与剪切强度设计方法。同时,为了提高同类型CFRP-金属胶接接头有限元分析的效率,使用Python编程语言开发了基于ABAQUS有限元软件的参数优化插件。开发的参数优化插件提供了CFRP-金属胶接接头有限元分析的自动前后处理功能,实现了基于胶接接头刚度平衡设计准则与剪切强度设计方法的参数优化功能。最后通过试验验证了仿真插件的准确性和有效性。Adhesive bonding is the most important way to connect carbon fiber reinforced plastic(CFRP) drive shaft with other components. Due to the uncertainty of bonding strength, it has become a common choice to study the rationality of adhesive layer design by using finite element software. In this study, the failure criterion, stiffness balance design criterion and shear strength design method of adhesive joint have been studied. Meanwhile, in order to improve the efficiency of finite element analysis of similar CFRP-metal adhesive joints, the parameter optimization plug-in is developed by using the Python programming language interface provided by ABAQUS software. The plug-in provides automatic pre-and post-processing function for finite element analysis of CFRP-metal bonded joints, the optimization function of stiffness balance design criterion and shear strength design method of adhesive joint is realized. Finally, the accuracy and reliability of the simulation plug-in are verified through experiments.
