The Model of Friction and Wear of the Elastic Coating against a Wavy Punch under Vibrations

Resumo

A mechanical model of friction and wear of an elastic coating against a wavy punch under forced oscillations (vibrations) is proposed. The model allows predicting reduction in the effective coefficients of friction and wear depending on the parameters of forced vibrations and waviness of the punch. Qualitative agreement between the obtained theoretical dependences and known experimental results is demonstrated. The proposed model can be used for correct interpretation of the results of tribological experiments.
