Vibrating screens play an important role in industrial production. While the cross beam fracture is the main reason for the shutdown of the screen. In order to solve the problem of fatigue fracture of the beam of the large-scale vibrating screen, the 3.6x7.3 m banana vibrating screen was taken as the research object, and the joint surface analysis was introduced at the joint surface of each part of the beam to simulate the stiffness and stress concentration of the joint surface, so that the nonlinear problems will be transformed into linear problems, and the stress and deformation of the connection area are correctly simulated, thereby this project has given an accurate basis for further optimization and optimizing the structure.
