Paper Title
Modeling, Analysis And Optimization Of A Four Cylinder Engine Crankshaft
Abstract
Crankshaft is large volume production component with a complex geometry in the Internal Combustion (I.C)
Engine. This converts the reciprocating displacement of the piston into a rotary motion of the crank. This paper consists of
static structural analysis of a four cylinder engine crankshaft. It identifies and solves the problem by using the modeling and
simulation techniques. The modeling of the crankshaft is created by using SOLID WORKS software and then simulate the
crankshaft for static structural analysis. Finite element analysis is performed to obtain the variation of stress of the crankshaft
by using SOLID WORKS software. The objective involves modeling and analysis of crankshaft so as to identify the effect of
stresses on crankshaft to compare various materials and to provide possible solution. Von-mises stress induced in the
crankshaft is 116.4845 N/m2
and shear stress induced in the crankshaft is 0.0014 N/mm2 in theoretical results. The values of
von-mises stress that comes out from the analysis are far less than the material yield stress and so our design is safe. Results
obtained from the analysis were then used in optimization of crankshaft. The optimization process resulted in a weight
reduction, increased strength and a reduced cost of the crankshaft.
