Abstract

In this study, influence of nut configuration on fatigue characteristic of bolt/nut assembly under transverse vibration has been investigated. In the experiments, the apparent fatigue limits were investigated for two bolt/nut assemblies tightened with a flange nut and a tapered nut. The results showed that the apparent fatigue limit of the bolt/nut assembly tightened with the tapered nut was higher than that of the flange nut. Its causes were revealed by FE Analyses. As the result, it could be seen that a difference of nut inclinations when the assembly received the transverse load caused the difference of fatigue limits. It was also seen that the nominal stresses at root of the first thread were different even if the same transverse load was applied to the bolt/nut assembly.
