超磁致伸缩材料(Giant Magnetostrictive Material,简写GMM)具有良好的微伸缩特性,开发基于GMM的微进给刀架,可以应用于微细加工领域。由于温度影响GMM棒的磁致伸缩特性,在研究GMM驱动的微进给刀架时,首先需要进行微进给刀架在微驱动过程中的磁热特性分析,分析热对其微进给特性的影响,并利用有限元技术对微进给刀架的磁热特性进行仿真,得到GMM棒温度沿轴向分布与作用电流之间的关系,为微进给刀架的实际应用提供理论基础。
Giant Magnetostrictive Material (GMM) has good micro-telescopic characteristics and the development of GMM-based micro-feed turret, which can be applied in the field of micro-machining. Due to the influence of temperature on the magnetostrictive properties of the GMM rod, when studying the GMM-driven micro-feed turret, we first need to analyze the magnetocaloric characteristics of micro-feed turret during micro-drive, The relationship between the temperature distribution along the axial direction of GMM rod and the acting current was obtained by using the finite element method to simulate the magnetocaloric characteristics of the micro feed turret, which provided a theoretical basis for the practical application of micro feed turret.
