Abstract

In this study, CAD model was developed for reciprocating piston of an IC engine using SOLIDWORKS (2017 version) modelling tool and was simulated at a speed of 600-3000 RPM. Reaction forces and linear velocity at different combustion time, thermal stresses, equivalent strains, resultant and displacement on the piston were determined. At an engine speed of 3000 RPM and 224NM torque, maximum displacement of 8.03x10-1mm, maximum equivalent strain of 2.152x10-2 and maximum thermal stress of 24.465N/mm^2. The maximum thermally induced stress value fell below the yield strength (460 N/mm^2) of the low alloy steel piston material, indicating that the material still has the capacity to accommodate stresses and deformations before its yield strength is exceeded. It was observed that the higher the engine speed, the higher the reaction forces and resultant displacements on the piston. The highest deformation value was recorded as 13,004.927 N/mm^2 which occurred at the point where the piston pin and one end of the connecting rod interlocks. Specific attention should be given to the selection of piston material and the intricate environment it operates, as it serves as the heart of a given IC engine.
