  • Three dimensional finite element stress analysis of circumferential distributed rod fastening rotor considering contact was performed.The evolution laws of stress distribution and interface contact status were revealed with different preload forces and operation conditions.The calculation results show that contact interface may separate locally and slide when the rod fastening rotor transmits power and lateral load,which results in its carrying capacity less than integral rotor.With the increase of preload force,rod fastening rotor can transmit greater load,but the maximum stress increases significantly and the strength margin of material decreases.According to the obtained stress level of rod fastening rotor and contact stress distribution and the ratio between tangential force and normal force of contact interface,the method for determining preload force of rod is given to ensure structural integrity and structural strength requirements.The analysis also provides references for preload force determination of such rod fastening rotor.
