Effects of Different Surface Structures on Vibration of Friction Coefficient between Cylinder Liner and Piston Ring

Abstract:

nfluential degree of different surface structures on stable output power of diesel engines under continuing work condition was evaluated, and relatively comprehensive reference optimizing micro-geometric morphology structure on cylinder liner surface was provided, through performing friction and wear experiments of cylinder liner and piston ring with three kinds of different surface structures: honing textured surface, no textured surface, and crater-grooved surface on an Optimal SRV IV oscillating friction and wear tester respectively, and analyzing effects of different surface structures on vibration of friction coefficient with power spectrum density. Results show that crater-grooved surface structure has smaller vibration value of friction coefficient under low loads and fluid lubrication state, while roughness determines vibration of friction coefficient under high loads and boundary lubrication state.
