摘　　要：描述了轻型矿用接近共振筛的结构特点和在具体的生产过程中所产生的问题。利用ansys9.0建立筛体的有限元模型,对振动筛进行模态分析,找出了振动筛筛框刚性较强和容易发生的疲劳断裂部位,得到了各阶模态下振动筛的固有频率,为进一步分析振动筛使用失效的原因提供了依据,提出了改进的方案。The description of structural characteristic and problems that occurred in the actual producing process were presented. By using the finite element software-ansys9.0, the model of light - duty resonance screen was established and the mode of light - duty resonance screen was calculated. The result showed the stiff part and the fatigue part of the screen. The natural frequency of screen was gained. The result provided the base for further analysis about invalidation and new method for evolution.
