Finite Element Analysis and Installation Optimization Design of Negative Pressure Vibrating Screen Exciter

摘要

In this study, to focus on the problems of a negative pressure vibrating screen, a three-dimensional model of the exciter and the screen is established by using the modeling software, and a finite element model of the screen is then established by the ANSYS software. The analysis of the screen model is carried out to evaluate the natural frequencies and vibration modes of the screen. Based on the analysis results, the constraints and the vibration conditions are imposed on the screen, and the harmonic response analysis is performed. It is concluded that under the condition of the same number of the vibration exciters, the effect of the screen filtration is improved by using the eight-shaped arrangement of the vibrating rods, compared with the parallel arrangement.
