FSAE赛车悬架碳纤维圆管与金属接头剪切应力的研究
Shear stress study of carbon fiber circular tube bonded with metal for FSAE car suspension
摘要
Abstract
Applying composite to FSAE car suspension is benefit to reducing both of the vehicles mass and sprung weight,and the connectors between carbon fiber composite circular tube and metal are often jointed by adhesive bonding technology.Based on some relevant hypotheses and boundary conditions,an equation of strain energy for adhesive joints was established to describe the response of axial load.According to the variational principle and the minimum potential energy principle,the distribution of stress in the mid-surf of adhesive was revealed.Comparisons between the analytical results and the finite element results show out that they are in good agreement with each other.So it can be deduced that the analytical model is reasonable for the stress evaluation of the bonding between the fiber circular tube and metal.Furthermore,influences of geometrical or material parameters to the shear stress distribution were investigated.Inherent characteristics of the adhesive bonding were given out which are helpful to optimize the mechanical behavior of the bonding in turn.关键词
