Abstract

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.
