摘　　要：以某一机械式振动台的台面为研究对象,利用UG对其进行了三维实体建模,然后以IGES格式导入有限元分析软件ANSYS Workbench,对其进行模态分析,得到了台面的前6阶振型和相应振型。经过对台面进行结构优化设计,提高了台面的固定频率,使其满足预定要求,同时也为整个台面设计以及后续的动力学特性研究提供了理论依据。Mechanical vibrator appending table was taken as the object of study and its^three-dimensional solid modeling was carried out by UG.It was saved as IGES format,then importing into the finite element analysis soft-ware ANSYS Workbench.The modal analysis was carried out to obtain the preceding 6 steps natural vibration fre-quencies and the corresponding vibration modes of the mechanical vibrator appending table.Natural vibration fre-quencies were increased by optimizing the structure of table to meet the desired requirements.At the same time,it provided theoretical basis of design of the whole table and further dynamic study.
