FATIGUE CRACK PROPAGATION RATE OF ZG35 STEEL WITH SEMI－ELLIPTICAL SURFACE CRACK
(Department of Mechanical Engineering; Xiangtan University; Xiangtan 411105)
Abstract: On a bowl body the occurrence frequency of surface crack which affectd the safety of the centrifuge has been evaluated scientifically. The growth rate of surface crack on the centrifuge bowl body(ZG35) has been determined, and the results of the experiment have been specifically analysed.
Key words: growth rate; surface crack; centrifuge bowl body
