Modal analysis for multi-angle vibrating screen based on ANSYS Workbench

The vibrating screen of Schenck SLO2496 banana type was researched,and the concrete data of dimension could be obtained through the field measurement.The three-dimensional model was established based on maintenance manual combined with the concrete data.Then it was transmitted into Workbench software,in which vibration modal analysis was completed.Meanwhile,the whole vibrating system was simplified as a single freedom vibration system by theoretical analysis,and then obtained the system natural frequency.Followed by the vibrating screen hammer test for experimental modal results,and finally compared with the finite element results to validate their reasonable.From the analysis result,the various order natural frequency and vibration mode are obtained.The vibration performance is obtained,which provide an essential theoretical basis for the optimization design.It allowed the excitation frequency as far as possible away from the resonance frequency range,and allowed the shaker resonate between the various components in use process,and improve the service life of the vibrating screen.Meanwhile,the analysis results can be used as essential theory basis for further dynamic analysis.
