Dynamic Search Structure Failure Path Method Based on Element Birth and Death Technology for Overhead Traveling Crane
For providing basic data to the reliability evaluation of the carrying capacity of the overhead traveling crane’s structure, by using Visual C++6.0 development platform, Pro/Toolkit and the element birth and death technology, the parametric model of the overhead traveling crane’s structure and the automatic analysis of the structure finite element model have been achieved. The results from the analysis obtained maximum element stress from each load step, and then the failure paths of the structural element which undered static load were found, from which the failure order consistented with failure development law of the overhead traveling crane’s structure, this would provide a technical basis to the search of dynamic failure paths which undered dynamic load. Finally, engineering examples which verified the feasibility of this method were brought.
