摘　　要：文中利用有限元分析软件ANSYS对大型直线型振动筛工作状态下的应力进行分析,得出振动筛的最大应力集中位于筛箱箱体侧板和筛箱支撑横梁连接处,筛箱箱体后挡板横梁处。根据迈纳尔损伤积累理论对振动筛最大应力处的节点进行疲劳寿命分析,分别得出振动筛最大应力节点的疲劳寿命,为大型振动筛的疲劳寿命设计奠定了基础。This paper mainly uses finite element software ANSYS to analyze the working condition of large linear vibrating screen. Results show that the maximum stress concentration comes from the screen box side plates and the supporting beams connection of screen box,the screen box rear cross beam. The Miner damage accumulation theory is used to analyze fatigue life of the maximum stress node of the vibration sieve,this method can provide reference for the design of fatigue life of large vibration screen.
