Abstract

Modern life is marked with the extensive use of machine tools. The latter stand for high consumers of electrical energy which increase carbon emissions. For this reason, various solutions aiming to reduce energy consumption in industrial sector are elaborated. One solution lies in the use of economical materials for the spindle rotation system supported by active magnetic bearings (AMBs), which corresponds to a problem that has never been undertaken so far. A new conception for machine tool spindle rotation system is elaborated for sustainable design. The spindle material is composed of a carbon epoxy hollow shaft wrapped with a steel layer and supported by AMBs. A Finite Element Method (FEM) modeling of the spindle rotation system was carried out to assess its dynamic consumed energy and power during the acceleration and cutting phases. For an accurate estimation, the power consumed by the spindle system was calculated taking into account the dynamic behavior of the cutting force and losses generated by the bearings. A comparison between energies consumed by the proposed spindle system and the steel spindle system was enacted.

带主动磁轴承的复合主轴的动态分析和能耗建模，促进可持续生产

现代生活的特点是广泛使用机床。机床消耗大量电能，增加了碳排放量。因此，人们提出了各种旨在降低工业领域能耗的解决方案。其中一个解决方案是在主动磁悬浮轴承（AMB）的支持下，使用经济型材料制造主轴旋转系统，这是迄今为止从未解决过的问题。为了实现可持续设计，我们为机床主轴旋转系统提出了一个新概念。主轴材料由碳环氧树脂空心轴和钢层组成，并由主动磁悬浮轴承支撑。对主轴旋转系统进行了有限元法（FEM）建模，以评估其在加速和切削阶段所消耗的动态能量和功率。为了准确估算，在计算主轴系统消耗的功率时考虑了切削力的动态特性和轴承产生的损耗。此外，还对拟议主轴系统和钢制主轴系统的能耗进行了比较。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
