THE ANALYSIS OF HOMOGENIZING OF BOND LAYER IN THE CARBON FIBER DRIVE SHAFT
摘要
Abstract
When the carbon fiber drive shaft is connected by adhesive transfers load, the stress in the end of bonding layer will be greatly enhanced while the middle part will be reduced, which causes the destruction of adhesive joint generates in the end of the bonding layer first, then affects the performance of the coupling.This article explains the adhesive bonding layer stress curve regular from the perspective of strain and puts forward several factors which influence the stress distribution of bonding layer.These factors involve internal and external circumferential deformation of bonding layer and the thickness of bonding layer.Then, we put forward several methods to homogenize the bonding layer stress, which were verified by the finite element analysis method.Firstly, increasing the bonding layer thickness can homogenize the stress while the degree of homogenizing is not obvious, and it will increase the bonding layer defects in engineering.Secondly, the drum-shaped adhesion with variable thickness bonding layer makes the stress homogenization of the bonding layer more obvious.At last, this article indicates several factors that affect the stress homogenizing of the drum-shaped adhesive bonding layer such as the length of variable thickness bonding layer (L) and the maximum thickness of bonding layer (H).关键词
