Abstract:

There are lots of distributed sources in the process of fatigue crack propagation of the lattice boom, static evaluation of the reliability indicators cannot be satisfied to solve practical engineering problems. The load and fatigue resistance regards as a random process, considers the fatigue failure of the randomness in a variety of factors, the concept of dynamic reliability of the weights index is proposed, models of dynamic reliability of the weights index are built based on the fatigue bearing capacity mode and limit damage degree mode. Fatigue stress experiments comparisons are doing during a crawler crane according to the actual operating conditions and a K-type welded joints prototype. The results show that the dynamic reliability evaluation assessment model is more accurately in the fatigue life evaluation and the method can provide a new assessment method for engineering applications.
