This work presents an investigation on wear prediction of multibody system including dry revolute clearance joint using a computational methodology. A procedure to analyze multibody system in which wear is present at revolute joints is presented. The study involves integrating a dynamics model of the mutibody system with clearance joint into a wear prediction procedure. The contact model in clearance joint is established using a hybrid nonlinear contact force model and the friction effect is considered by using a modified Coulomb friction model. The wear modeling of revolute clearance joint in multibody systems is presented based on the Archard's wear model. Finally, an academic four-bar multibody mechanical system with revolute clearance joint is used as numerical example application to perform the investigation.
