Finite Element Analysis Of Crankshaft & Connecting Rod Of Internal Combustion Engines

Abstract

Crankshaft & Connecting Rod are the two critical components of Internal Combustion Engine as both are the critically loaded & experience cyclic loads in the form of bending and torsion during their service life. This paper represents the structural analysis of crankshaft & connecting rod by considering the dynamic forces. Dynamic forces calculation is carried out for every crank angle & maximum of this force is used as boundary conditions for the finite element analysis. Structural Analysis was done using Hypermesh 8.0 & Optistruct 8.0 as a tool for FEA. Graphs are plotted for the variation of force with the crank angle. Different plots for stress & deformation under loading conditions were plotted .The stresses at the critical locations were found out to be within the permissible limits.
