摘　　要：利用三维建模软件对振动筛进行实体建模,并利用有限元方法,对模型结构进行合理简化。通过有限元软件计算出了筛体结构的固有频率、固有振型,为振动筛的大型化设计提供了理论依据。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.

关 键 词：振动筛 有限元 模态特性
