Introduces the working principle of the main vibrator and designs the structural form of the feeding device of main vibrator.By SolidWorks,the 3D modeling is carried out,and the finite element model is established with ANSYS Workbench software.Tetrahedral mesh is adopted and the rounded corner is divided with encryption,and the definition of full constraint is set.The modal analysis is carried out by using the modal solver,obtaining the structure model,finite element model,natural frequency of the first to fifth orders and the vibration mode diagram of each order.The natural frequency of the feeding device of the main vibrator rises steadily from the first to the fifth order,among which the third natural frequency is 51.056 Hz,which is close to the excitation frequency and in a sub-resonant state.Therefore,the vibration stability of the main vibrator can be ensured by the resonance principle,and the vibration mode is mainly the rotation around y axis and up-down vibration along y axis,which conforms the actual working conditions of material transportation,and proves the accuracy of the model establishment and the excitation frequency setting.
