Dynamics and screening characteristics of a vibrating screen
Optimal design of a vibrating screen also contains the innovative design of screen body. A novel high-strength large vibrating screen with duplex statically indeterminate mesh beam structure was invented [85,95], and the theoretical analysis, the FEM analysis and the experimental validation were conducted to investigate its dynamic characteristics The structure of a real vibrating screen is particularly complicated and mainly comprises a screen box, screen mesh, and vibration exciters. A simplified three-dimensional model of the vibrating screen, shown in Fig. 1, is established to reduce the complexity but realize the actual screening effect.Additionally, the sieving process in the Stepwise shape optimization of the surface of a vibrating screen
