The Effects of the Swing of the Vibration Screen with Double Masses on the Properties of Two-Stage Vibration Isolation

The effects of the swing on the vibration isolation properties of the vibration screen with double distributed masses are studied by means of analysis on the mechanical model of six-freedom degrees, The analytical formulas of natural frequencies of the screen with symmetrical and distributed masses and responses for harmonic excitation are derived. Compared with the discreted model,a practical method to determine the two-stage vibration isolation parameters concerned with swing of the screen is presented and a practical example is calculated.
