摘要

This paper presents a new approach for the dynamic analysis and driving control of CNC machine tool with the support of virtual machine tool technology. The dynamic characteristics of both mechanical and electric parts are reviewed for a whole transmission system from servo motor, through ball-screw to translational working table. The investigation introduces a new approach of obtaining transfer function of multibody systems. Hence an example of controller tuning based on acquired results is implemented. Modeling and simulation of machine tools are executed for the method validation. The investigation indicates that this new approach is applicable for dynamic analysis and control of multibody systems, specially deduces a solution for some dynamically complex systems.

本文介紹了虛擬機器分析工具技術的支援下的數控工具機之動力學分析與驅動控制的新方法。將具有各種動態特性的機械零件和電氣零件進行整合。整個傳動系統從發電機，通過滾珠導螺桿使得工作台橫向平移。本研究引入取得多體系統傳遞函數的新方法。因此實現一個基於標準通用控制器調校的例子來展示分析結果。藉由工具機的建模與模擬驗證方法的執行來闡明這種新方法適用于多體系統的動態分析與控制，特別是針對一些複雜動態系統的解決方案。
