摘　　要：用模态分析可以确定一个结构的固有频率和振型,固有频率和振型是承受动载荷结构设计的重要参数。故以该主轴基座为研究对象,利用三维软件SolidWorks建立了其三维模型,并使用有限元分析软件ANSYS对基座进行模态分析。分析得到基座的前十阶固有频率远大于基座的振动源频率,主轴基座在工作过程中不会发生共振。Modal analysis is used to determine the natural frequency and vibration mode of a structure, which are significant parameters in under dynamic load structure design. With the spindle base as the research object, SolidWorks is used to build a 3D modal and the ANSYS is adopted to make a modal analysis on foundation support. The result of this research shows that the first ten natural frequencies are much greater than the b the vibration source frequency and the Spindle base will not produce resonance when it works.
