Abstract
An analysis model of wear coupling with mechanical dynamics behavior was established, and the numerical simulation scheme of the model was proposed to investigate interaction between dynamics and wear of machine. A sliding wear simulation approach based on Archard's wear law and finite element methods was proposed, in which progressive accumulation of wear in metal hinge was simulated with ANSYS. Removal of material caused by wear was implemented by moving boundary nodes. Possible mesh distortion due to repositioning boundary nodes was settled using boundary displacement method from structural shape optimization. Clearance joint was modeled by replacing the kinematical constraint with force constraint, which was applied as external forces into multi-body dynamics equations. Sequential coupling mode was used chatacterize wear and dynamic during different life stage. The proposed method is an efficient tool to predict the life of mechanical components considering the effect of wear, the method improves design efficiency.
