Abstract
Currently, there are many researches to improve the efficiency and capacity of the vibrating screen. Usually, multi-slope vibrating screens use an unbalanced exciter to produce a circulating radial force of the same frequency on both drive shafts. This produces an alternating force in the direction of the exciter stand due to the circulation of the imbalance weights. The basic working parameters, such as the forces acting on the bearings of the drive shafts and the supporting springs, the amplitude, velocity, acceleration, and orbit of the screen surface, have an important role in the design of a vibrating screen. These parameters are usually determined by establishing a vibrating model and solving the technical vibrating problem. However, this method does not give high accuracy because it simplifies the vibration model of the screen. To make simulation results more accurate, this study builds a 3D model of the vibrating screen and uses a dynamic multi-body simulation to determine the basis working parameters of the screen. The correctness of dynamic simulation research is verified through experiment. This work would provide some guidance for designing and studying vibrating screen with flexible construction and working parameters.
