THREE-DIMENSIONAL FINITE ELEMENT ANALYSIS AND ALLOWABLE DEFECT ASSESSMENT OF THE CENTRIFUGE BOWL BODY
(Mechanical Engineering Department，Xiangtan University，Xiangtan 411105)
Abstract: For the first time，an allowable defect analysis of the bowl body of XZZ 120p-G Cen-trifuge was made by wing fatigue fracture mechanics method;and，again for the first time, the designfatigue curve of the dangerous scetion of the bowl body was given out，which may form the basis for thedesign and use
Key words: of the centrifuge.bowl body of centrifuge fatigue fracture mechanics method crack
