Numerical Analysis of a Nonlinear Vibrating Two-Degrees-of-Freedom System with Various Friction Models

Abstract

The dynamics of the two-degrees-of-freedom system, constituted of two bodies interacting with the weightless plate having harmonic displacement in different environments, is analyzed in this paper. Resistance of the environment is described by four different friction models: Coulomb friction model, Coulomb viscous model, Coulomb-Stribeck model and the LuGre friction model. The paper is mainly focused on changes in vibration of masses depending on the friction model. The analysis is conducted by monitoring displacements of the masses and phase-space diagrams.
