Simulation analysis on start-up process of large linear vibrating screen

According to the working characteristics of the linear vibrating screen,a model of forced vibration caused by the eccentric mass was built based on vibration mechanics.The exciting force loading data which more corresponded to the actual conditions was estimated,and the motion laws of the start-up process of the vibrating screen were obtained through simulating with MATLAB.And the stress distribution and the deformation laws of the vibrating screen were obtained by the time-dependent analysis with ANSYS,which offered references for structural design and optimization of the vibrating screen.
