- •
The nature of crossover phenomena of gearbox vibration data is explained.
- •
A set of novel features containing clear physical meaning are proposed.
- •
A piecewise-linear regression model is used to extract the features automatically.
- •
The proposed method can discriminate types and severities of gearbox faults.
