摘要/Abstract

摘要： 机床能量效率的评价是机床能效优化研究的基础。现有评价方法主要集中在机床加工过程的能量效率评价，对支持高能效机床设计的机床自身能量效率评价研究还存在不足和问题。为此，提出表征机床自身能量效率的机床固有能量效率新概念；它是机床加工能力范围内的未来可能的所有加工过程的综合平均能量效率。分析了机床固有能量效率的内涵，提出了机床固有能量效率的有效描述法即虚拟工件法；建立由固有比能效率、固有能量利用率两个综合评价指标和待机功率、当量启动能耗、当量空载功率、当量附加载荷损耗系数四个单项指标构成的机床固有能量效率评价指标体系；基于虚拟工件法，进行上述机床固有能量效率综合评价指标的获取方法研究，实现了机床固有能量效率评价。应用案例研究验证了所提方法的可行性和实用性。该方法可为高能效机床的设计、新制造系统的设计与组建以及高能耗设备改造提供支持，从而提升机床使用生命周期全过程的综合能量效率。

Abstract: Energy efficiency assessment for machine tool is the basic of its energy efficiency improvement. The existing researches of energy efficiency assessment mainly focus on the machining process of machine tool. However, the study on the nature energy efficiency assessment of machine tool, which is able to support the design for energy-efficient machine tools, is defective. A concept of inherent energy efficiency (IEE) which represents the nature energy efficiency of machine tool based on energy consumption characteristics of machine tool is presented, and the IEE is the integrated energy efficiency of various processes. The connotation of inherent energy efficiency of machine tool is analyzed and an effective way for describing IEE named virtual workpiece method is proposed. An assessing index system, including two comprehensive indices (inherent specific energy consumption and inherent energy efficiency) and four single indices (standby power, equivalent starting energy, equivalent unloaded power and equivalent additional load loss coefficient), is built. Moreover, the obtainment method for the inherent energy efficiency indices mentioned above are built based on the virtual workpiece, aiming to access internal energy efficiency of machine tool. The case study shows the practicability of the method presented. The method plays an important role in designing energy-efficient machine tools, designing and developing new manufacturing system, as well as rebuilding high energy consumption equipment, which would contribute to improving the comprehensive energy efficiency of machine tools during the use phase of lifecycle.

Key words: energy assessment, inherent energy efficiency, machine tools, virtual workpiece
