Abstract
According to life evaluation of the crane fatigue crack formation, starting from the micro-level of cracking formation, the local stress-strain method is used, in conjunction with the modified Neuber method, to build the life evalu-ation algorithm for crane fatigue formation. Based on the equation, factors affecting the fatigue cracking formation are stud-ied and analyzed, in order to get the influencing rule and size of each factor and put forward the design and production sug-gestions, providing practical meaning for application.关键词
