Application of Simulated Fatigue Analysis to Design of Hydraulic Powered Roof Support

The simulated fatigue life cycle prediction is studied.Through the simulated fatigue test and life cycle prediction conducted to the hydraulic powered roof support,it could not only predict the remaining life cycle of the current hydraulic powered roof support,but also effectively guide the RD of new type hydraulic powered roof support,so as to improve the domestic design level of hydraulic powered roof support,which has very important theoretical significance and practical value.
