| Abstract: | In this paper,the fatigue experiment principle,method and process of the spot welded components under the vibration environment are introduced;some experiment results that are the reflections of some of their fatigue properties are presented.The mech- anism of the vibration fatigue destory is discussed and analysed.At last,the p-s-n curve of the crack initiation and the p~*-s~*-n~* curve of the fracture are given,by use of which the service life assessment and the durability analysis are able to continue. |
