摘　　要：滑枕是数控机床重要功能部件,为机床主轴系统提供了安装支撑,并与滑座通过导轨连接形成直线运动。滑枕在动态载荷下的振动量级、固有频率、刚度对数控机床的动态性能是重要影响因素。模态分析可以获得结构特征参数,为结构系统的振动特性分析和结构动态特性的优化提供依据,是研究结构动态特性的重要手段。The ram is an important functional part of the CNC machine tool, providing installation support for the machine tool spindle system, and is connected with the sliding seat through the guide rail to form a linear motion. The vibration level, natural frequency and stiffness of ram under dynamic load are important factors that affect the dynamic performance of CNC machine tools. Modal analysis can obtain structural characteristic parameters, provide a basis for analyzing the vibration characteristics of structural systems and optimizing structural dynamic characteristics, and is an important means to study structural dynamic characteristics.
