Root cracks in gears are a typical fault in gear transmission, posing a threat to the operational safety of gear systems. As one of the important internal excitations of the gear transmission system, the change of stiffness can well reflect the dynamic response of the gear, so the accurate stiffness algorithm can effectively analyze the dynamic characteristics of the gear system.
