On the Oil Film Behaviour of Piston Rings : Correction of Effective Pressure Region of Oil Film
Transactions of the Japan Society of Mechanical Engineers, 1977 This paper reports on a theoretical calculating procedure of the oil film behaviour between the piston ring and the cylinder wall. The analysis assumes: (1) that the sliding surface of the ring may be approximated by a parabola; (2) that the oil film viscosity is constant; and (3) that the trailing end of oil film pressure varies according to the ...
