N2 - The contact between real rough machined surface is simulated using a multilevel contact model in this paper. The model divide total surface deflection into macro and micro scale two parts. They are also calculated at the macro and the asperity level, respectively. Wavelet is used to decompose and reconstruct macro-scale contact model. Micro-scale contact model is established based on FFT method. Real asperity density and asperity radius are calculated from an FFT performed of the surface profile at asperity level. Finally, A real machine surface is simulated with this model on elastic and elasto-plastic contact.
