Abstract
To evaluate and compare the fatigue performance of two competing manufacturing technologies Computer aided modelling and optimization analysis of crankshaft is done for two automotive crankshafts namely AISI-4140 alloy steel (EN 19C ) and ASTM A536 100-70-03 (GGG7O). A dynamic simulation was conducted on two crankshafts, AISI-4140 alloy steel (EN 19C ) and ASTM A536 100-70-03 (GGG7O) from similar single cylinder four stroke engines. Finite element analyses have been 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 mentioned analysis were used in optimization of the forged steel crankshaft. Geometry, material and manufacturing processes were optimized considering different cost, manufacturing feasibility and constraints. The optimization process included geometry changes compatible with the current engine ,fillet rolling and result in increased fatigue strength and reduced cost of the crankshaft, without changing connecting rod and engine block.
