The crankshaft is a high volume production component with a complex geometry in the internal combustion engine (IC). This converts the reciprocating displacement of the piston into a rotational movement of the crank. In this paper we intend to study the static analysis in a single-cylinder, 4-stroke, crankshaft I.C. Crankshaft modeling is created with the CATIA-V5 software. The finite element analysis (FEA) is performed to obtain the variation of the stress at critical locations of the crankshaft using ANSYS software and applying the boundary conditions. Then the results are drawn Von-loss induced voltage at the crankshaft is 15.83Mpa and the cut-off voltage is induced at the crankshaft is 8,271Mpa. Theoretical results are obtained by von-misses stress is 19.6Mpa, the shear stress is 9.28Mpa. The validation of the model is compared with the theoretical results and FEA of the Von-misses voltage and the shear stress are within the limits. In addition it can be expanded for different materials and dynamic analysis, crankshaft optimization.
An extensive review of the literature on the crankshaft was performed by zoroufi and fatemi (2005). In this study we present a study of the literature on the evaluation of the performance of fatigue and compression of the forging steel and the ductile iron crankshaft in its operating condition of the crankshaft specification of study and various sources of combustion. The survey includes a review of the effect of the in-fluent ions parameter, such as residual stress on fatigue behavior and the method is inducing a residual compression stress in the crankshaft. Therefore, we follow the stress analysis and model analysis of 4 cylinder crankshafts. Fem Ansys software was used for analysis of vibration model distortion and stress states are crank. The relationship between the frequency and the vibration model is explained by the analysis of the crankshaft model. This provides a valuable theoretical basis for the optimization and improvement of the motor design, the maximum deformation appears in the center of the surface of the collar of the sleeve.
