Crankshaft is large volume production component with a complex geometry in the diesel engine. This converts the reciprocating displacement of the piston into a rotary motion of the crank. The crank shaft takes the power from piston which is generated due to combustion process inside the combustion chamber of the cylinder. During the power transmission process the load acts at a particular crank angle to the max and hence the connecting rod is analysed for the stress developed, due to load conditions and the changes mentioned. In the present work Statics structure ANSYS is done to find out maximum von misses stress and deformation in the crankshaft of diesel engine. Material is taken in this paper of crankshaft is Structural steel. In this paper we have used 4 stroke petrol engine crank shaft of Honda Unicorn bike (149.2cc). The modeling of the crankshaft is created using SOLIDWORKS Software. Finite element analysis (FEA) is performed to obtain the variation of stress at critical locations of the crank shaft using the ANSYS software and applying the boundary conditions. Presser is applied on the crankshaft is 5MPa in the form of load. The objectives involve modeling and analysis of crank shaft, so as to identify the effect of stresses on crank shaft. Optimization is done in the crankshaft design and ANSYS is done after optimization. The results are compared of crankshaft stress and deformation before and after optimization in design. Results are coming best in the optimized design of crankshaft.
