Statics and modal analysis for large vibrating screen

The 3D modeling software of Solidworks was used in the paper for the 3D modeling of large banana vibration shaker. And then the 3D model was imported into Ansys Workbench for finite element analysis. The overall stress and strain distribution of the shaker could be got under static loading. Secondly, the analysis of the dynamic characteristics of the entire shaker should be done, and the modal frequencies and mode shapes could be got through the analysis of the modal analysis results. Finally, the hammering test was done to verify the theoretical analysis. And it also provided a necessary theoretical basis for the design and improvement of the entire shaker.
