| 摘 要： | 铝合金在采用对接接头胶接时能保证连接强度,但其应力分布不容易分析.通过数值分析方法,在ANSYS软件平台中通过搭建两种不同形式的铝合金对接接头,研究模型弯曲时其应力分布情况.胶层应力在两端部分波动较大,在中间应力分布比较有规则,X、Y与第一主应力与胶结长度几乎成线性分布,而胶层的平均应力关于胶层的中点位置几乎呈现对称的抛物线分布.基于以上规律可以为铝合金在受到载荷时对接头的设计提供一定的方法和建议.

| Abstract: | The aluminum alloy is butt-joint as structural adhesive can afford enough bonding strength,but the stress distribution is hard to analysis.This paper uses the finite element method in ANSYS software platform building two different butt-joints models of the aluminum alloy,the stress distribution of the bondline when suffered the flexural moment as flow,the bonding stress unsteadily on the both sides,and regularly on the middle party.X,Y stress and major principal stress linear distribution with the bondline,... |
