ZK3654同步直线振动筛的横梁在实际使用过程中出现裂纹，采用高阶实体单元建立振动筛筛箱的有限元模型，进行谐响应分析，确定振动筛工作状态下的动态应力分布，找出最危险截面。同时用 Creo2.0软件建立振动筛三维实体模型，确定质心位置。分析结果表明，原设计存在一定的缺陷，为此提出改进方案，并对改进后的结构进行分析计算，证明了该方案的有效性。

The ZK3654 synchronous linear vibrating screen breaks in the actual use.A high-order entity unit is used to construct a finite element model of the vibrating screen box,and the har-monic response analysis determines the dynamic stress distribution in the working condition of the vibrating screen,finding out the most dangerous section.A 3D solid model is established by the Creo2.0 software to determine the location of the centroid.The analysis results indicate that the original design has some defects.Accordingly,the author of this paper puts forward an improve-ment scheme,analyzes and calculates the improved structure,and proves the effectiveness of the proposed scheme.
