摘要
以实验用YR－924型振动筛为研究对象，用有限分析方法（FEM）对其筛框金属结构进行动态计算分析，求出其固有频率和模态振型。
Taking an experimental YR-924 viberatory screen as studying object, through the finite element analysis method (FEM),the metal structure of sash is analyzed by dy-namic calculation, deriving its frequency inherent and modal vibration shape, and its results are made an analysis
