Most studies of bolted joint fatigue have been conducted for a bolted joint subjected to only axial vibration or only transverse vibration. However it is considered that the actual bolted joints are subjected to multi-axial vibration. Bolted joint fatigue under multi-axial vibration, axial vibration and transverse vibration, has been investigated in this study. In the experiments, the two types of vibrations were applied to the bolted joint with same phase and with different phase. The results said that even if the bolted joint was subjected to multi-axial vibration, the fatigue strength was the same as the uni-axial fatigue strength. However the apparent fatigue limits were different according to the vibration conditions.
