Loads and working conditions of the trapezoidal cross-section of 36 m span crane beam can be analyzed by finite element method. Firstly, analysis of the stress and deformation is completed under the dangerous condition of crane beam based on the ANSYS software; secondly, find out the stress concentration and fatigue crack sensitive area of the bearing; finally, capture the position of fatigue crack. All these methods can provide strong basis for implementing effective monitoring to the state of the crane beam stress. Thus, ensure safe operation of equipment and improve equipment utilization rate in work.
