On the frictional contacts in multibody system dynamics

Abstract

A comprehensive analysis on the use of different friction force models on the dynamic simulations of multibody systems is presented in this study. In this context, the most relevant approaches for dealing with friction available in the literature are revisited, classified into the statics and dynamics models. In this process, the main limitations and implications of the friction force models are briefly described. The dynamic response of a single-mass one degree-of-freedom system is utilized to analyze and compare the various friction laws. The results obtained suggest that the prediction of the dynamic behavior of multibody systems strongly depends on the selection of the appropriate friction model as well as frictional parameters.
