The Analysis of the Influencing Factors about Friction and Wear Characteristics of the Piston Ring in Stirling Engine

Abstract:

The problem about friction and wear characteristics of piston ring which is directly related to the sealing properties of stirling engine was analyzed. An improved seal structure of piston ring was taken as the research object, the influence of the temperature and the pressure of refrigerant were considered when the friction and wear characteristics of piston ring in stirling engine was studied. The calculation formula about radial weal amount of the piston ring with the change of the temperature and the gas pressure was derived by using the peeling wear theory. Then, the experiment was taken to confirm these formulas. The results show that the formulas were right. Hence, a viable way to analysis the sealing properties and life prediction method of piston rings was got.
