Abstract: Substitute actual component by structure model in research program can not only save money but also consumption of time and the results are satisfactory. Writer of this paper made a structure model to study the stress distribution and fretting fatigue of blade to disc circumferential dovetail joint. The slot in disc and tenon in blade have been analysed and tested. The research results were satisfactory as what have been hoped. The research method is useful for not only dovetail joint but other machine tenon joint as well.
