Résumé

The integral method was used in a previous research to identify the damping model but this technique has some limitations in estimating the damping model in a gear system including time-varying loading conditions. To overcome these limitations, the integral method is reformulated in this research to identify the damping model on spur gear pair system including variable loading. The motion equations presented in terms of integrals, including time-varying loading conditions, are solved by linear least squares method to characterise the constant piecewise model. Continuous wavelet transform method is used to validate the constant damping model. The new methodology is tested with a signal obtained from numerical simulation.
