摘要: 运用ABAQUS有限元分析软件对某三轴转台模型进行模态分析,得出该转台的谐振频率及振型。通过对三轴转台进行了结构上的改进,提升了转台的谐振频率值。最后进行随机响应分析,输出转台上某结点的加速度曲线。这些相关数据和曲线为三轴转台的振动试验提供了理论支持。

Abstract: By using finite element analysis software ABAQUS, a model analysis of a three-axis turntable was carried out, and the model′s inherent frequency and vibration type was obtained. By improving the structure of the threeaxis turntable, model′s inherent frequency is increased. In the end, by carrying out random response analysis of the model, the acceleration curves of a node in the model are output. These data and curves can support vibration experiment of threeaxis turntable.
Key words: Finite element analysis, Random response, Three-axis turntable
