Abstract

Fatigue is an important failure mode for swing frame of mine trunk. However, swing frame have so many attributes that it is difficult to analyze their fatigue damage using experimental measurement methods. In this paper the stress and strain analysis of swing frame is obtained by MSC.Patran software with the help of the dynamic analysis from MSC.Adams software. Improved model of swing frame is made according to stress concentration. The fatigue life predictions of unimproved and improved swing frame are achieved via the theory of cumulative damage in fatigue by MSC.Fatigue software. The results show that the fatigue life of improved swing frame is extended and satisfied with the practical application.
