Friction characteristics between cam and follower are numerically calculated using an approximate method. The model is based on partial EHL theory which consists of a film thickness formula[Ref.1] modified from Pan-Hamrock's formula[Ref.2]) considering surface roughness and the mean contact pressure-compliance relationship (GW model[Ref.3]). The effects of non-Newtonian behavior of lubricant and surface temperature rise are taken into account for the calculation of friction force. The result of this approximate method is compared with the previous study (Tanaka et al. [Ref.4]) which solved simultaneously Reynolds equation, elasticity equation, etc. and the experimental results obtained by a made apparatus similar to the system. The validity of approximate method is also examined, for mainly the effects of amplitude and directional properties of surface roughness.
