There are three ways for the material particles moving on the vibrating screen surface:sliding down, sliding up and jumping. Through the kinematic analysis for 5XF150/180 type vibrating screen, we could obtain the the actual movement process of material particles on the screen surface within a cycle, then establish the mathematical expression of impact load of material on screen surface. Using ANSYS Workbench to perform static and transient analysis for sieve bodies, we could get the dangerous points and load spectrum of fatigue analysis. Appl...
