Motion Simulation of Dual-Frequency Vibrating Screen

Abstract:

In order to reduce screen plugging and screen pasting, improve the efficiency of screening, a kind of dual-frequency vibrating screen was introduced. It had been used three exciting motors. We established the mechanical model of this vibrating screen, and used Matlab-simulink software to analyze the trajectory changes of screen surface, influenced by mass moment rate, initial phase differences and installation position between high and low frequency exciting motors. The results of the study indicate that, the rate of mass moment and difference of initial phase angle have great influence on the motion trail pattern and amplitude of vibration of the screen, and the installation position of high-frequency exciting motor have less influence on screen surface trajectory under the condition of exciting motors’ parameters given in this article. When designing dual-frequency vibrating screen, we can use the method of this paper to select appropriate rate of mass moment, difference of initial phase angle and so on, and achieve the expected motion trajectory of vibrating screen.
