Contact problem of die regular relief motion over viscoelastic base

The numerical and analytical model is constructed to calculate the deformation friction force component when the regular relief die moves over the viscoelastic base, which is modeled with the Kelvin body with the relation time spectrum. The developed friction model is applicable to both the discrete and full contact between interacting surfaces. The die regular relief is modeled with a set of surface points. The results obtained with the developed model are compared for the case of full contact with the analytic calculation. The sliding velocity and the die regular relief shape are studied to identify the influence on the contact characteristics and the deformation componentof the coefficient of friction.
