| Abstract: | The solid models of vibrating screen have been built by using 3D soitware and predigested by using finite element method. The natural frequency and the natural mode of vibrating screen have been calculated by the software for FEM, proposes the theoretical basis for the design of large- sized vibrating screen. |
