- •
An analytical mesh stiffness calculation model is proposed for cracked spur gears.
- •
The model enables accurate mesh stiffness calculation for both small and larger cracks.
- •
The effectiveness is verified by comparing with FE results.
- •
An 8-DOFs gear dynamic model is developed to reveal the fault vibration features.
