摘要/Abstract

摘要： 建立了碳纤维传动轴刚度不平衡胶接接头的有限元模型,对扭转载荷下刚度不平衡胶接接头的失效行为进行分析,预测了胶接接头的失效扭矩和失效模式,并进行扭转实验证明有限元分析方法的有效性,最后研究了被粘物剪切模量比和壁厚比对刚度不平衡胶接接头失效行为的影响,为工程上碳纤维传动轴胶接接头的设计提供了参考。

Abstract: A finite element model was established to analyze the failure behavior of unbalanced adhesive joint in carbon fiber drive shaft under torsion loading. Then the failure torque and failure mode of the unbalanced adhesive joint was predicted from the finite element model. It is found that the failure torque, failure mode in the torsion experiment were in close agreement with the result from finite element analysis. The effect of shear modulus ratio and wall thickness ratio between metal shaft head and carbon fiber tube on the failure behavior of unbalanced adhesive joint are discussed, which provides available reference in designing adhesive bonded joints in carbon fiber drive shaft.

Key words: carbon fiber drive shaft, adhesive joint, stiffness unbalance, failure behavior
