Numerical analysis of single cylinder engine crankshaft

Abstract. In this static analysis has been performed for the crankshaft of four stroke single cylinder engine under fatigue
stacking conditions. The primary target of this work is to demonstrate the crankshaft with measurements and accelerate
the crankshaft for static and fatigue analysis. The business programming SOLIDWORKS 2013 is utilized for displaying
the wrench shaft. The analysis programming ANSYS 14.5 is utilized for static and fatigue analysis of crank shaft. The
finite element analysis was done for the current model of a 150cc motor crankshaft. The outcome shows that the greatest
stress happens at the intersection of crankpin-crank arm and crankpin-main bearing journal. To acquire better life and to
expand the life of the crankshaft, some structure adjustments were made by shifting the plan parameters in the overallcrankshaft. Three models of crankshaft were acquired by presenting a different blend of structure parameters, for
example, oil opening profundity, filet sweep, wrench geometry and crankpin gap to the Existing model. The quality andthe life of the altered crankshafts were acquired by finite element analysis. The outcome of the current model and thechanged models are looked at. From the examination, Modified model II shows preferred outcome over the other
crankshaft models as far as quality and life.
