摘要：The residual stress of crankshaft fillet is an important factor to influence service life of crankshaft. To improve the strengthening effect of compressive residual stress of large crankshaft fillet more efficiently and cost-effectively, a new method of fillet mechanical impact process was proposed. In order to explore the feasibility of this way, ABAQUS was used to study residual stress in surface and depth of fillet under different processing parameters. The simulation results show that several parameters including impact angle, impact speed and impact rotation angle are key factors to influence the impact strengthening effect of residual stress. Only by selecting optimized parameters can the desired strengthening effect be achieved. The simulation analysis also provides a foundation for further experimental fillet mechanical impact test.
