Deformation and stress analysis of crankshafts for single cylinder and four cylinder ic engine using ansys
Abstract
The crankshaft is one of the most important loaded components in the engine, as it is experiencing cyclic loads in the form of a bending and torsion. In the study, crankshaft of the single-cylinder engine and crankshaft of the four-cylinder engine were designed in the SOLID WORKS software. Then these designs were transferred to ANSYS software with finite element method. Both crankshafts were compared in terms of stress and deformation. Critical areas had been identified as a result of stress and deformation. Comparative analysis of both shafts was not found in the literature. As a result, the values of stress and deformation increased as the speed increases in both shafts. Stress and deformation increased as the pressure increases associated with the speed applied on the crankpin journal. The stress in the crankshaft of the single cylinder engine was critically occurring on main journal, and the stress in the crankshaft of the four-cylinder engine was critically occurring on the crankpin journal. This much of the stress in the single cylinder engine crankshaft reduces the working life of the shaft. The shaft material should be selected considering the working conditions in crankshaft, or the material should be improved by coating the main journal and crankpin journal.
