The crankshaft is one of the most critically loaded components as it experiences cyclic loads in the form
of bending and torsion during its service life. Its failure will cause serious damage to the engine so it’s important at the
time of design to verify fatigue strength and torsional vibration and physical validation on test bed as well as on field
vehicles. More challenges in crankshaft design due to increasing vehicle payloads, lower weight requirement, higher
efficiency and longer durability life. This paper will give an overall guideline for the student and industry engineers for
designing the crankshaft which can serve the longer durability life without any failures.
