Dynamic analysis of fretting-wear in friction contact interfaces

Résumé

A numerical treatment of fretting-wear under vibratory loading is proposed. The method is based on the Dynamical Lagrangian Frequency Time method. It models unilateral contact through Coulomb's friction law. The basic idea is to separate time in two scales, slow scale for tribological phenomena and fast scale for dynamics. For a chosen number of periods of vibration, a steady state is assumed and the variables are decomposed in Fourier series. An Alternating Frequency Time procedure is performed to calculate the non-linear forces. Then, a Hybrid Powell's algorithm is used as solver. Numerical investigations on a beam with friction contact interfaces illustrate the performances of this method and show the coupling between dynamical and tribological phenomena.
