Abstract
In order to examine low cycle fatigue life of a die used for component rolling of lag screw bolt, stress analysis was conducted by three-dimensional elastic-plastic analysis software FORGE. The form rolling simulation carried out with two dies arrangement, and performed it by the position control which fixed a principal axis interval. As a result of stress analysis, the position which the maximum of major principal stress in a dice generates was corresponded well with the position which the fatigue crack actually occurred. When analyzed by changing dice rotating speed with 10, 30 and 60r/min, the maximum of major principal stress became small in the case of 30r/min. This cause is presumed for tangential force of the dice to increase by reduction of the oil film effect due to generation of heat, while deformation resistance of a material becomes small so that rotating speed increases.
