摘　　要：针对振动筛筛网磨损快、筛条更换困难的情况,通过对筛网结构进行分析研究,提出了一种可拆卸化又可减振的振动筛筛网,该筛网具有筛条更换快捷方便,节约维修时间,筛条损坏速度慢,延长筛条的使用寿命,保护筛板不损坏等优点。并对筛网进行了模态分析,获得了筛网的固有频率与固有振型,结果表明筛网不会发生共振现象。For quick wear of the vibrating screen mesh and the difficult of screen bar replacement, proposes a removable and damping of vibrating screen mesh by the analysis of screen mesh structure. The screen mesh has some advantages which the replacement of a screen bar is quick and convenient, it saves maintenance, screen bar damage is slow, screen bar prolongs the life and it protects that screen plate is not damaged. It obtains the natural frequency and vibration model of the mesh screen by the modal analysis of screen mesh. The screen mesh don＇t occur resonance.
