【Abstract】 In order to study the running in between the cyclinder and the piston ring,a tribosystem has been established,and the running in is regarded as a self adapting and convergent process of this system.With the RMS σ and wear rate W· considered as the two characteristic parameters of the system,a mathematical model for running in based upon the theory of mixed lubrication and dynamic wear is presented.The model allows the effects of engine operating conditions and surface topography on running in to be studied in detail.更多还原
