This article establish the mechanics model of pendent axis of tube style centrifugal machine, analysis and calculate the fatigue and fracturesafety property of pendent axis.
Based the numerical simulation for sphere tank with defects, fracturesafety assessment and stress strength verification are done under the cases of working pressure and over pressure.
