摘　　要：以某加工中心主轴部件-主轴箱体为例,应用有限元分析法分析了主轴箱体的模态特性参数,得到主轴箱体振动的前5阶固有频率和相应振型,采用比利时LMS设备对该模型进行测试验证。结果显示,理论模态参数与试验模态参数的相对误差小于7%,各阶振型一致。The modal parameters of the headstock of a CNC lathe were analysed based on the finite element analysis method （FEA） through an example of a machining center headstock. The first 5 natural frequencies and corresponding vibration modes were obtained. The FEA model of the head- stock was verified by LMS equipment made in Belgium. The simulation results indicate that the relative error between the theoretical modal parameters and the experimental modal parameters is below 7% with the vibration modes of all steps in consistency.
