| description | A method of damage detection and fault diagnosis for gears is presented based on the
theory of elastomeric dynamics according to the theory of cracked beam. It takes an advantage of
accurate fault diagnosis of gear body using the change of dynamic features and has some
advantages 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 gear
dynamics characteristics caused by the position and size of crack are deeply investigated by
comparison with FEM. The theoretical analysis results are contrasted with numerical simulation
results and shows good agreement with the result by FEM. The proposed method can be used to
detect damage and diagnose fault for gear structures and also can be applied to designing dynamic
characteristics for gear systems. |
