MATHEMATICAL MODELING OF PISTON RING ADAPTABILITY TO THE INTERNAL COMBUSTION ENGINE CYLINDER SLEEVE WALL

We present the equations and a detailed algorithm for solving the contact problem of piston ring conformance with the cylinder sleeve wall. The practical realization of this complex problem has made it possible to improve the reliability of the sealing of the cylinder/piston group of the internal combustion engine. In the calculations we use the Winkler foundation model and the finite-difference and matrix forms of the equations with normalizing of their coefficients.
