The numerical calculation module for piston rings

The piston with piston rings and bearing surface is a self-contained and highly complex tribological system. One of the most widespread global friction pairs traversed by reciprocating a pair of ring - cylinder liner piston - rings - cylinder internal combustion engine. Group PRS combustion engine is the solution generating considerable friction. Various researchers estimate the share of friction losses, per node piston rings - cylinder liner, at 19 to 60% of the total friction losses in the combustion engine. This paper describes part of a larger program to reduce wear the set working parts (piston, piston ring and bearing surface). The project is implemented through the development of new designs of piston rings with anti-wear coating that contains synthetic diamond in the form of loose embedded in a coating of chromium (PRS). The aim of the authors was to present the methodology used to compute characterized by a particular procedure. In practical use FEM software is used and the FVM. Developed and implemented Piston Rings Calculation Module is compatible with the idea of numerical computational methods is to say: functionally consists in carrying out a calculation of the desire to achieve the exact solution (the nearest is real) by conducting and receiving intermediate solutions (the next).
