| Research Abstract |
This study has been achieved to establish the design method of a bolted joint subjected to various vibrations. We established the design method of a bolted joint subjected to transverse vibration at first. Next, I developed an experimental apparatus to investigate fatigue characteristics of a bolted joint subjected to not only transverse vibration but also axial vibration, and conducted the fatigue tests using he developed apparatus. At present, I am establishing the design method of a bolted joint subjected to transverse vibration and axial vibration. An influence of nut configurations to the fatigue characteristic of a bolt such as the wheel hub bolt was also revealed in this study.
