| Abstract: | The calculation methods of invalidation performance under a given degree or circle degree under a certain probability of non-invalidation were researched,by using both crack-leng before fatigue fracture as output parameter and drift principle in reliability technic.A example was also presented,in which the reliable design was used to counter-fracture intensity of loader boom at the condition of a given circle degree and reliability. |
