Effects of Deviated Excitation on the Swing of the Vibration Screen with Single Mass

The swing problems of single mass vibration screen caused by the excitation and asymmetric structure are studied,based on the analysis on the mechanical model of single mass and multi-degrees of freedom. The analytical solution of the natural frequencies and dynamical responses of the vibration screen model with transverse asymmetric structure are derived. The effects of structure parameters on the frequency response properties of the vibration screen are discussell combined with a practical example of the screen model
