Abstract
This study reports on a method of making the fatigue design of bolted joints. Two types of bolted joins are treated - one is the simplest cylindrical joint. The following conclusions are obtained through stress analysis and fatigue tests of the above-mentioned bolted joints; (1) A method is proposed for expressing the load applied to the bolt in joints by plotting the dynamic stresses of the bolt on Haigh diagram, taking the maximum load and the preload as parameters; (2) A stress analysis of the T-flange bolts is performed. The analytical results show good agreement with the experimental results measured with strain gages; (3) It is verified by the fatigue test that fatigue design of the T-flange bolts can be done by comparing the above-mentioned load and the fatigue strength of the bolts.
