Abstract:
The static structural and dynamic loads were analyzed analytically which, results in the
load applied to crankpin bearings. The study selection of best material by comparing the
Static structural analysis on a crankshaft from a single cylinder crankshaft. The need of
load history in the FEM analysis necessitates performing a detailed static and dynamic
load analysis. Therefore, this study consists of two major sections: (1) static and load
analysis, (2) FEM and stress analysis. In this study static and dynamic simulation was
conducted on three crankshafts Forged steel (AISI 1045 steel), Ductile cast iron and
Medium carbon steel.. Finite element analysis was performed to obtain the variation of
stress magnitude at critical locations. Finally select suitable material.The stress and
dynamic analysis was done analytically and was verified by simulations in SOLIDWORK
which resulted in the load spectrum applied to crankpin bearing. This load was then
applied to the FE model in ANSYS, and boundary conditions were applied according to
the engine mounting conditions. The analysis was done for different engine speeds and as
a result, critical engine speed and critical region on the crankshafts were obtained.
The value of von-misses stresses of analysis is less than the material yield stress so this
design is safe. By comparing von-mises stress and deformation values, from three different
materials Therefore the finite element results show that the forged steel (AISI 1045 steel
material) is the best material of all. The maximum load occurs at the crank angle of 355
degrees for this specific engine. At this angle only bending load is applied to the crankshaft.
