Dynamic modelling of a one-stage spur gear system and vibration-based tooth crack detection analysis
Time varying gear mesh stiffness is investigated for cracked tooth gear. A new 12 DOF beside three other models are applied to simulate the same gear system. Dynamic simulation is performed to study the obtained dynamic response for all crack cases. Third model (8 reduced to 6 DOF) is adequate for modelling the symmetric disc case. The developed model is the more accurate for modelling the asymmetric disc case.
