Numerical simulation of sliding wear based on archard model

Abstract

A sliding wear simulation approach based on Archard's wear model was proposed, in which ABAQUS scripting interface was used to simulate the progressive accumulation of wear between contact surfaces. Removal of material caused by wear was implemented by moving boundary nodes. In order to measure wear rates of woven fabric liner, a pin-on-disk experiment was performed. The wear rate of 9.76×10−7mm3/Nm was used as input of the simulation. Then a wear problem of spherical plain bearing with self-lubricating fabric liner was performed to validate above wear prediction method. Compared with wear experiments of other bearings, close agreement between experiments and wear simulation was found. At the same time, proper re-meshing technology and time step would increase calculation efficiency and precision. Results show that the complex nonlinear wear process can be simulated with a series of discrete quasi static models and the method proposed can be widely used to predict wear problems for engineering.
