Review paper on Static Structural Analysis and Simulation to Obtain Stress Magnitude at Critical Location of Crankshaft in Internal Combustion Engine

This study presents a static structural analysis and simulation to determine the stress magnitude at critical locations of a crankshaft in an internal combustion engine. The crankshaft, a crucial component in engine performance, experiences significant mechanical stresses due to the forces exerted by the pistons during operation. The analysis was performed using finite element analysis (FEA) to model the crankshaft’s behavior under static load conditions. A crankshaft model was created in Pro/ENGINEER and subsequently imported into ANSYS software for simulation. The primary objective was to identify the stress distribution across the crankshaft and pinpoint areas of potential failure. The results reveal that the stress concentrations occur at specific critical locations, which are prone to fatigue failure under prolonged cyclic loading. By comparing the stress magnitudes in forged steel and cast iron crankshafts, it was found that the forged steel crankshaft exhibited lower strain levels, indicating better performance and higher durability under static loads. This analysis supports the conclusion that the forged steel crankshaft is not only capable of withstanding the applied stresses but also suitable for mass production, potentially leading to cost reductions. The findings of this study contribute to the optimization of crankshaft design, enhancing the overall efficiency and reliability of internal combustion engines.
