Abstract: Running-in should be regarded
as a convergent process of a dynamic wear system. The wear
volume W and the rms of the composite profiles are chosen as the
state variables of the system. Two state equations, the wear
equation concerning the effect of surface roughness and the rate
equation concerning the changes in rms during the running-in
process, have been established. The optimum roughness σp and the
equilibrium roughness σe, the system stability and critical load
carrying capacity, and the optimum loading curve for improving
the efficiency of running-in, have been predicted and simulated
by the dynamic system model.
