Modal Analysis of Vibrating Screen Based on UG

The vibrating screen structure is modeled and the finite-element modal analysis is conducted by UG software. Through the analysis of the free mode and condition mode,the natural frequency and the vibration mode of the vibrating screen structure are figured out under the two modes. The result shows that the valuable reference data is provided for the design of the vibrating screen structure. The exciting frequency of the vibrating screen's vibration motor is much smaller than its the least natural frequency in the case of its free mode and condition mode,so the resonance phenomenon of the vibrating screen structure does not happen.
