摘　　要：采用ANSYS有限元分析软件,建立了大型冷矿振动筛的有限元模型,对其进行了结构动力学分析。基于分析结果,为解决振动筛筛箱强度问题提出了一种新的结构改进方案,有效降低了振动筛的应力值,对振动筛的设计具有重要的意义。With the software ANSYS, the finite element model of the large cold sinter vibrating screen is built, and the structure dynamics analysis of this model is carried out. On the basis of the analysis results, a new structural improving plan is put forward for resolving the strength of the vibrating screen deck. The stress on the screen deck with the new structure can be decreased effectively, which is of great significance for the design of the vibrating screen.
