摘要
高速电主轴是高性能数控机床的关键功能部件,对高速电主轴的热传导理论模型进行了研究,利用基于模型的试验设计(DOE)与优化方法,建立了电主轴冷却系统DOE分析流程。通过对影响冷却系统性能的4个变量进行正交试验,明确了影响电主轴温升的主要因素,为高速电主轴的冷却结构优化提供了指导。通过冷却系统DOE实验,大幅节省了实验资源,提升了工作效率,缩短了产品研发周期。
Since high-speed motorized spindle is the key component of high performance CNC machine tool,the theoreticalmodel of spindle thermo-conduction has been analyzed in this paper in order to establish the spindle DOE analysis procedureby using the model-based DOE and optimisation. According to the orthogonal experiment of 4 varibles which would affect thesystem performance of the cooling system,the principal factor acts on the spindle temperature can be determined and the spin-dle cooling structure can be optimized. It is shown that experiment resourses can be saved and the efficiency as well as the de-velopment period can be improved and shortened by using the DOE.
