Design and Analysis of Crankshaft of Three Cylinder Engine

The crankshaft plays a pivotal role in ensuring the internal combustion engine’s efficiency and precision. To enhance its design parameters, an optimized crankshaft is proposed. Through computer simulations, two different materials (grey cast iron and cast iron ENGJL100) are selected for the crankshaft, and their equivalent stress, total deformation, equivalent elastic strain, and directional deformation are computed. This paper focuses on analysing the materials used for the engine's crankshaft and conducting structural strength tests in accordance with specific requirements. The crankshaft model is developed using SolidWorks 2018 software. The study concludes that grey cast iron ENGJL100 is a suitable material for the crankshaft, exhibiting superior strength and durability when placed in the designated location within the design.
