COMPARISON ANALYSIS OF CRANK SHAFT
Journal Title: IJAR-Indian Journal of Applied Research - Year 2016, Vol 6, Issue 7
Abstract
The overall objective of this study was to evaluate and compare the fatigue performance of two competing manufacturing technologies for automotive crankshafts, namely forged steel and composite material. In this study a dynamic simulation was conducted on crankshaft, forged steel, metal matrix composite, E glass epoxy, Kevlar 29 and carbon epoxy composite, from similar single cylinder four stroke engines. Finite element analysis 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 achieved 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 the use of metal matrix composite and carbon epoxy composite, resulting in increased strength of the crankshaft, without changing connecting rod and/or engine block.
