摘　　要：以有限元分析与模态分析理论为基础,建立基于UG-NX5造型软件平台的BIG-PLUS工具系统三维几何模型,并根据实际工况建立有限元模型,利用ANSYS软件对施加有位移约束的有限元模型进行了前四阶模态分析,得出固有频率和振型,为数控机床BIG-PLUS工具系统的动力特性设计和模态实验分析提供了重要的依据。With finite element analysis and modal analysis theory as a foundation, three-dimensional geometric model of the BIG- PLUS tool system was built based on UG-NX5 configuration software platform, and the finite element model was set up on actual working condition. Using ANSYS software to analysis the finite element model imposed displacement constraints, natural frequencies and vibration mode shapes of the first four modal were obtained. It provides an important basis for dynamic characteristics design ,and experimental modal analysis on BIG-PLUS tool system for NC machine.
