Finite Element Analysis of Small Marine Diesel Engine Crankshaft

In this paper, with the ANSYS, stress distribution and safety factor of crankshaft were analyzed by using 3D finite element method. The results show that the exposed destructive position is the transition circular bead location of the crank web and the crankpin. Maximum stress is 121 MPa. Safety factor is 3.12. Maximum deformation is 0.0719 mm. Crankshaft satisfies the design requirement.
