摘　　要：高效成型数控铣齿机床中的结合面对铣齿机的动态性能有很大影响,因此,研究铣齿机结合面的动态特性是准确预测铣齿机结构特性,提高其性能的前提条件。针对大型数控铣齿机床系统建模的复杂性,提出了基于多种软件(Pro/E、ANSYS与ADAMS)集成的刚-柔耦合建模技术,用弹簧阻尼单元模拟了铣齿机结合面,通过ADAMS/Vibration模块求解了系统在稳定切削过程中主轴箱的振动频率和模态振型,并用LMS噪声振动仪器进行了工况测试,仿真结果与实测结果相吻合,从而为铣齿机的结构优化奠定了基础。Faying face in high efficient forming CNC milling machine tools will affect their dynamic performance greatly.So it is a precondition of forecasting and improving performances of milling machine tools to study the dynamic characteristics of the facying face.Concerning the complexity of modeling large NC milling machine,a rigid-flexible coupling modeling is proposed based on a variety of intergrated software（Pro/E,ANSYS and ADAMS）.Besides,the the spring-damp system is used to simulate the faying face.Then the vibration frequency and vibration modes of the spindle box is obtained by using ADAMS/Vibration module during the stable cutting process.Furthermore,vibration is tested by LMS equipment which results are agreed with the simulatiom results.Thus it provides a basis for optimizing of the milling machine structure.
