摘　　要：介绍了MN-1型三电机自同步振动筛的有限元分析、模态试验方案、测点布置、激振点选择和试验过程。通过模态试验对该结构参数进行识别,得到电机激振频率附近的有关模态参数。对进一步和优化结构提供了借鉴。The paper introduces MN-1 type self-synchronous vibration screen withthree motors about its finite element analysis, testing program formodality, distribution for measuring point, choice for exciting point andtest process. By modality experiment, the paper determine its structural parameter, makes out relevant modality parameters near excitingfrequency of motor, which offers reference for further modification andoptimization for structure.
