摘要
应用有限元方法研究了螺纹根部圆弧半径对螺栓强度的影响,通过改变圆弧半径缓解螺纹根部的应力集中,改善了应力分布,从而实现提高螺栓疲劳强度的目的.
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.
