NUMERICO-ANALYTICAL ANALYSIS OF PROCESSES OF DYNAMIC CONTACT OF CYLINDRICAL MACHINE PARTS

L.P. Vovk, B.V. Sobol

Mathematical aspects of the solution of spatial contact dynamic problem of con-tacting the cylindrical details of cars are considered. Updating of the method of the superposition is presented, that allows to conduct analytical research of the in-tense-deformed condition and to make practical recommendations according to intensity of local concentration of pressure in irregular zones of contact that prac-tically predetermines strength parameters of the contact pair. The mechanical characteristics of interaction of piston fingers of internal combustion engines with the head of the rod and piston lugs are considered as a numerical experiment.
