摘　　要：以SLO3661型直线振动筛激振梁为研究对象,利用ANSYS Workbench有限元分析软件进行模态分析,得到其前10阶固有频率和振型,并与实际测得的激振梁固有频率进行比较,排除了其存在共振的可能性;进一步进行谐响应分析,得到动态响应特性,确定了其结构的薄弱部位;并对其进行疲劳分析,验证其抗疲劳强度,对激振梁的结构改进及优化具有重要意义。Taking exciting beam of linear screen SL03661 as a research object, apply ANSYS Workbench finite element analysis software for the modal analysis, the first 10 natural frequencies and corresponding modes are obtained, which is compared with the actual measured natural frequency to rule out the possibility of resonance; then the harmonic response analysis is can＇ied out to obtain its dynamic characteristics for ascertaining its weak part; and fatigue analysis is accomplished and its fatigue resistance is verified, it is of great significance to improve and optimize the structure.
