摘　　要：振动筛是原煤实现分级和洗选加工的重要机械设备。为了确定振动筛的振动特性,防止其在使用过程中发生共振现象,减少噪音,采用ANSYS Workbench软件对振动筛进行模态分析。得到了其前12阶固有频率和振型,验证了振动筛的工作频率是否远离了固有频率,对振动筛的安全、可靠、高效生产具有重要意义。Vibrating screen is an important equipment which is used for raw coal classification and washing. In order to confirm the vibration characteristics of vibrating screen equipment, prevent the resonance in the prncess of using and reduce noise,this paper applies the ANSYS Workbench software to confirm modal analysis on the vibrating screen.The first ten natural frequencies and corresponding modes are obtained from the modal analysis, and it can verify whether the working fi＇equency of the vibrating screen is away from the natural frequency.It could be ot great significance to the safety, reliability and efficient of the vibrating screen.

关 键 词：振动筛 模态 固有频率 有限元
