Structural Static Analysis of Crankshaft

B. Mounika | Madhuri.R.P

Abstract: Crankshaft is one of the vital components for the effective and precise working of Internal Combustion engine with the complex geometry, which converts the reciprocating displacement of the piston to a rotary motion. In this paper an attempt is made to study the Static structural analysis on crankshaft from single cylinder 4-stroke I. C Engine. The 3-Dimensional Modeling of crankshaft is done using Catia V5R20 software and Finite element Analysis is performed by using ANSYS Software by applying boundary conditions as the sides fixed and pressure spectrum is applied in the middle of crankpin. Bending moment causes the tensile and compressive stresses, Twisting moment causes Shear stresses. Thus, Analysis was conducted on the crankshaft with three different materials cast iron, High carbon steel and Alloy steel (42CrMn) to obtain variation of stress magnitude at critical locations. Analysis results are compared with Theoretical results of von-misses and shear stress which are in the limits to validate the model.
