Coupled mode parametric resonance in a vibrating screen …
Download PDF Abstract: We consider a simple dynamic model of the vibrating screen operating in the parametric resonance (PR) mode. This model was used in the course of designing and setting of such a screen in LPMC. The PR-based screen compares favorably with conventional types of such machines, where the transverse oscillations are excited directly.

A novel vibration isolator for vibrating screen based on
A vibrating screen is widely used in raw coal screening, but intensive resonance in the startup and shutdown stages shortens the service life of the vibrating screen and generates vibration damage to surrounding buildings. Therefore, we designed a novel vibration isolator based on a magnetorheological damper, aiming to improve the vibration isolation performance …

Hence, to tune out the vibrating screen from the resonance by the second natural mode around the 2 ×, 3 × harmonics (30, 45 Hz) of the main excitation frequency (15 Hz), it is required to change the total stiffness of bolted joints by 2.63 × 10 7 N/m, which corresponds to the frequency deviation by at least ± 3 Hz.
