BACKLASH EFFECT ON SIDEBAND STRUCTURES OF GEAR PAIRS’ VIBRATION SPECTRUM abstract
A gear pair model including local tooth defects and backlash is considered and its response to parametric excitation is evaluated to include the sideband structures due to local tooth defects. Piecewise-linear and hysteresis formulations are considered for impact forces due to backlash. The response with hysteresis energy dissipation is shown to have a clear and stronger appearance of sideband structures. The model resembles the physical merits of the system and can be used for fault detection exercises with more confidence.
