| Abstract: | By using Finite Element Analysis method, this paper investigates the influence of the radius of screw thread roots for the strength of rail bolt. Through changing the radius of screw thread roots, the stress concentration was reduced, and the stress distributing was also ameliorated. So the fatigue strength of the rail bolt was improved. |
