Dynamic analysis and parameter optimization of combined multi-layer linear vibrating screen

In order to alleviate the fatigue damage caused by resonance in the combined multi-layer linear vibrating screen, this study conducted modal and harmonic response analysis using Workbench finite element analysis software. The results showed that there was a resonance risk at the 9th natural frequency. By optimizing the thickness of the side plates (increasing it by 4 millimeters), the frequency was successfully removed from the working range. This paramete optimization significantly improved the dynamic performance and reliability of the structure, providing a solid theoretical basis for design.
