Особенности задания граничных условий нестационарной задачи теплопроводности поршня дизеля

Abstract

The stationary and non-stationary models of the operation of transport engines have been analyzed by using the example of a third-class tractor diesel. The estimation of the resource strength of the edge of the combustion chamber of the piston is made taking into account the change in the rotational speed of the crankshaft. The control functions of the boundary conditions of the thermal conductivity of the piston in the zone of piston rings are determined, which are necessary for modelling the main transient processes of the non-stationary model of diesel operation. The work is performed on the example of a diesel engine 4ЧН12/14.
