Methodology for Calculating the Stress–Strain State of Internal Combustion Engine Parts in the SolidWorks System

Abstract

The stress-strain state of the piston of an internal combustion engine (ICE) and its components is studied using the method of contact interaction with a cylinder-piston group. To conduct the study, a marine four-cylinder four-stroke non-reversible cylinder engine without supercharging with a reversible gear transmission, a cylinder diameter of 85 mm and a piston stroke of 110 mm, 4HSP8.5/11 was used. An algorithm is derived that takes into account the deformations of the contacting parts. A technique has been developed for calculating the stressstrain state of a piston with oil-removing and compression rings. This method consists in solving systems of differential equations, which are represented by the relationship of various parameters of a solid deformable body.
