Abstract

Dynamic models are vital for gear diagnostics since they allow to study the physical phenomena occurring during their operation. Most of the existing models focus on spur gear, while a dynamic model for helical gears is still missing. This study suggests an accurate method for helical gear modeling called "multislice". According to this method, the helical tooth width is divided into infinitesimal slices connected in parallel, considering each slice as a spur tooth. The extended model with the multislice method was validated experimentally for a healthy gearbox, showing similar behavior. Comprehensive analysis which examines the behavior of the vibration signal in different operating conditions was conducted based on the simulations and used for model validation. This extended model holds a great potential to assess the detection capabilities of different faults at different severities and operational conditions.
