| 摘 要： | 共振是机械结构不可避免的问题之一,利用大型有限元分析软件ANSYS对设计的结构进行模态分析,将有效预估结构的振动特性及结构的优化设计。文章以主轴箱为例,运用该软件建立了主轴箱的三维有限元模型,在0～200Hz频率范围内,分析了该主轴箱的前十阶振型,结果表明:该主轴箱的主振频率处于62Hz,为主轴箱的整体设计及其制造提供了有力的技术支撑。

| Abstract: | Sympathetic vibration is one of the important problems in machine structure.Designed structure can be modeling analyzed using finite element analysis codes ANSYS,and the results will effectively estimate the vibration characteristic and the optimal design of structure.The model analysis about spindle box is shown as an example,this paper establishes the 3D finite element model of the spindle box on ANSYS.The first ten vibration modes of the spindle box are analyzed in the 0-200 Hz frequency range,the result shows that the major mode's frequency of the spindle box is 62 Hz and provides a powerful support of the technology for the whole design and manufacture of the spindle box. |
