Statics and modal analysis of large-scale banana vibrating screen

A large-scale banana vibrating screen was modeling by using SolidWorks, and then the 3D model was imported into ANSYS Workbench for FEA. The stress and strain distribution of the vibrating screen at static loading was obtained. In addition, the dynamic characteristics of the screen were analyzed also, and frequency and vibration shape of each order of mode were obtained according to modal analysis results. At last, the analysis results were verified through hammering test. The study offered necessary theoretical references for design and improvement of the vibrating screen.
