Abstract：Based on the basal principle of power balance a dynamic model of vibrating screen load-bearing beam was proposed using a Ritz-series method. The effects of additional forces caused by appendages of load-bearing beam, including mass of screen, vibrator and damping spring, were analyzed. The natural frequency, vibration mode and dynamic parameters of the beam were also theoretically calculated. The results show that the theoretical data agree well with the experimental data. The dynamic model based on power balance and Ritz-series method possesses the advantages of lower order, well computational stability and precision. The dynamic characteristic parameters of the beam can meet the engineering requirements and provide convenient kinetic analysis and calculation method for the dynamic design of large linear vibrating screen beam.
