摘 要：In order to reduce ring-liner interface friction power loss,this paper focuses on the structure parameters of the top ring,and investigates how the value of those parameters will influence top ring-liner friction power loss and the minimum thickness of oil film at top ring-liner interface.A mixed lubrication model is developed to simulate the effect of varying design parameters on ring-liner *** study shows that ring-liner friction power loss will be reduced with decreased axial ring height and barrel *** study provides a theoretical basis for design the top ring with reduced friction power loss at ring-liner interface.
