摘要
针对我国变频调速数控机床使用量大和能耗严重的问题,全面分析这类机床的能量传输规律,为进一步的节能研究提供理论依据。通过建立变频调速类数控机床主传动系统的能量流模型,分析机床主电动机功率传输特性和机械传动系统功率传输特性及其各部分的能量损耗规律;建立整个主传动系统的动态功率平衡方程并论述了该功率平衡方程相对于普通机床功率平衡方程的三个特点;最后,应用分析和实践展示了上述功率平衡方程的广阔应用前景。
In view of the characteristics of energy transmission in the running processes of numerical control （NC） machine tool driven by variable voltage variable frequency （VVVF）, an energy flow model of main driving system is established. The power transition characteristics of main motor and mechanical transmission system and the energy loss on every section are analyzed. Finally, the dynamic power balance equation of the whole main drive system is established. Comparing with the equation of common machine tools, this equation has three characteristics. The wide application prospect of the equation is shown by the application analysis and practices.
