Volume : II, Issue : VII, August - 2012 Modelling, Analysis And Comparison Of Forged Steel And Cast Iron Crankshaft Ram.R.Wayzode, P. G. Mehar, V. N. Mujbaile Published By : Laxmi Book Publication Abstract : compare the fatigue performance of two competing manufacturing technologies for
automotive crankshafts, namely forged steel and ductile cast iron. In this study a static
simulation was conducted on two crankshafts, cast iron and forged steel, from similar
single cylinder four stroke en-gines.Finite element analyses was performed to obtain the
variation of stress magnitude at critical locations. The dynamic analysis was done
analytically and was verified by simulations in ANSYS. Results achived from
aforementioned analysis were used in optimization of the forged steel
crankshaft.Geometry,material and manufacturing processes were optimized
considering different constraints, manufacturing feasibility and cost.The optimization
process included geometry changes compatible with the current engine,fillet rolling and
result in in-creased fatigue strength and reduced cost of the crankshaft, without
changing connecting rod and engine block. Keywords : Article : Cite This Article : Ram.R.Wayzode, P. G. Mehar, V. N. Mujbaile, (2012).
