METHOD BASED ON THE APPLICATION OF BACKWARD DIFFERENTIATION FORMULAS (BDF) AND ITS MODIFICATIONS FOR CALCULATING OF DYNAMICS FOR THE TRIBOSYSTEM OF PISTON ENGINES

Konstantin Gavrilov, Arseny Asaulyak, Ilya Kopyrkin

Abstract


Modifications of the BDF-method as applied to the calculation of trajectory of the moving elements of piston machines were analyzed. On the example of the calculation of the connecting-rod bearing of "Ruston & Hornsby 6VEB-X MK-III" engine as an international standard for testing we estimated the effectiveness of proposed algorithms for solving the equations of motion.

Keywords


tribosystem of piston machines, differential equations, order of BDF-method, hydromechanical characteristics.
