利用大型有限元分析软件ABAQUS，建立了三轴椭圆等厚振动筛筛箱的有限元分析模型，对振动筛筛箱进行了模态分析和动应力分析，得到了固有频率和相应的主振型，以及应力分布状态。指出了原筛箱结构存在的设计不足，并提出了改进措施，使结构各阶固有频率远离工作频率，应力分布更加均匀，系统动态特性得到了明显改善。

Using large-scale finite element analysis software ABAQUS , established the finite element model of three-shaft elliptical equal-thick screen .Carried out modal analysis and dynamic stress analysis .Calculated the natural frequency and the relevant vibration mode , the dynamic stress distribution state of the screen box .Pointed out that design deficiencies of the original screen box structure , and put forward the improvement measures which make the structure of each order natural frequency far from working frequency , stress distribution is more homogeneous , system dynamic characteristics has obviously improved .
