摘要
采用有限元分析软件ANSYS建立单搭自冲铆接头模型,对接头进行静力分析,在此基础上结合ANSYS/FE-SAFE,基于正弦激励载荷,对单搭自冲铆接头的疲劳寿命和安全系数进行了分析,得出自冲铆接头的最大应力位置与疲劳破坏位置一致,均为上板与铆钉头接触的部位。从安全系数云图中可得到工作安全系数大于许用安全系数,满足条件要求。用ANSYS/FE-SAFE软件来进行疲劳分析可以为下一步研究提供一定的参考。
Using the finite element analysis software ANSYS,the single lap self-piercing riveted joints model was established,the model will be used in static analysis.Based on static analysis,used ANSYS/FE-SAFE to analyze the fatigue life and safety factor under conditions of the sine excitation load,from the analysis of that,drew a conclusion that fatigue damage and fatigue destroy were both founded on the faying surface of upper sheet and rivet.From the safety factor and cloud maps,we can conclude that operating safety factor is bigger than permitted safety factor,which meet the need.It can provide reference for further research through fatigue analysis using ANSYS/FE-SAFE.
