Research on Identification of the Structural Interface Parameter of Machine Tool Orbit with Slip Mass

在模态分析的基础上应用弹簧-阻尼单元建立机床导轨滑块的结合面动力学有限元模型,经过优化计算来识别机床导轨滑块结合面参数。结果表明:优化计算方法识别参数结果与简化单自由度方法所得的测试结合面参数相近,该方法又是识别机床导轨滑块结合面参数一种有效方法。

On the hasis of the model the FEM of dynamics up by the spring-damp element. Using optimizing method, the structural interface parameter of machine tool orbit with slip mass is obtained. It is shown that they are close using optimizing method and identification of single free. This method can be used to distinguish the interface parameter of machine tool orbit with slip mass also,
