Notes:
A method of damage detection and fault diagnosis for gears is presented based on thetheory of elastomeric dynamics according to the theory of cracked beam. It takes an advantage ofaccurate fault diagnosis of gear body using the change of dynamic features and has someadvantages for dynamic design of gear systems.The dynamics characteristics, i.e., natural frequency,vibration shape,dynamic response and so on, due to crack of gear tooth are studied, and the geardynamics characteristics caused by the position and size of crack are deeply investigated bycomparison with FEM. The theoretical analysis results are contrasted with numerical simulationresults and shows good agreement with the result by FEM. The proposed method can be used todetect damage and diagnose fault for gear structures and also can be applied to designing dynamiccharacteristics for gear systems
