Abstract
In this research paper, estimation damping in spur gear pair system using Integral method and the continuous wavelet transform based approach (CWT) is proposed. In the first method, the motion equations of the model describing the system are reformulated in terms of integrals that give a set of linear equations solved by linear least squares method to allow a new methodology that starts with a constant piecewise model to bootstrap the most suitable model of damping. The constant model is validated using the wavelet demodulation approach that's based on the envelope extraction procedure to obtain the damping ratio associated with structural modes. In order to show the ability to predict the response, damping estimation procedures are tested on a signal obtained from numerical simulation of the spur gear pair system.
