摘　　要：机床量大面广,能耗总量巨大,提升机床能量效率已经成为发展绿色制造的重要内容。如何选择合适的机床能效测试方法是支撑机床设计、用户采购、运行优化和节能改造等场景下提升机床能量效率的基础性问题。为此,首先总结和比较了八种能效测试方法的内涵和特点,包括参考样件法、参考过程法、比能法、组件定标法、ISO 14955-3标准、GB/T 40735标准、固有能效潜力评估法和固有曲面法。然后,从五个场景(指导高能效机床优化设计、评选高能效机床制定能效标签等)和七个维度(操作耗时程度、操作难易程度、机床对比适用度等)评价机床能效测试方法。其中,运用层次分析法(AHP法)确定特定场景下七项评价指标的权重因素和各项评价指标下八种能效测试方法权重因素,并通过一致性检验来验证评价结果的有效性和准确性。Machine tools are in enormous quantity and consume great amount of energy.Improving the energy efficiency of machine tools has become an important part of the development of green manufacturing.It is a fundamental problem to select appropriate test methods for machine tool energy efficiency in the scenarios of machine tool design,user procurement,operation optimization and energy saving transformation.Therefore,the connotation and characteristics of the eight energy efficiency testing methods were summarized and compared,including reference part method,reference process method,specific energy consumption method,component benchmark method,ISO 14955-3 standard,GB/T 40735 standard,inherent energy efficiency potential assessment method and inherent surface method.Then,the energy efficiency test method of machine tools was evaluated from five scenarios(guidance for optimal design of high energy efficiency machine tools,selection of high energy efficiency machine tools and design of energy efficiency labels,etc)and seven dimensions(time required,simplicity of the test method and comparison of machine tools,etc).The analytic hierarchy process(AHP)is used to determine the weight factors of seven evaluation index in specific scenarios and the weight factors of eight energy efficiency testing method under each evaluation index.The validity and accuracy of the evaluation results were verified by consistency test.
