A Simulation Model of Piston Ring Pack designed by Matlab

Matlab is a powerful mathematical simulation software, which is widely used in many scientific fields such as theoretical analysis, engineering design, etc. In this paper, a Matlab program was written, and used to set up a poor lubrication model of piston ring pack. In this simulation model, the effect of surface roughness between cylinder-piston ring pack was considered, and an improved piston ring condition was used. Besides, this Matlab program was applied to diesel PA6-280 piston ring pack. At last, the minimum oil film thickness distribution curve was obtained within a working cycle of each ring.
