摘要
以镗铣加工中心电主轴为研究对象,以环境温度和对流换热系数为边界条件,分析电主轴在热载荷作用下的热传递规律,得出该电主轴在热稳定状态下的温度场三维分布。基于热结构耦合理论,研究电主轴的应力应变的变化规律,为高速电主轴的结构设计与优化提供了理论依据。
Based on boring and milling machining center spindle,under the conditions of the environment temperature and con-vection heat transfer coefficient of boundary,heat transfer law of the motorized spindle under the action of heat load was analyzed.The distribution rule of the spindle in three-dimensional steady-state temperature field was gotten.Based on the coupling theory of thermal structure,the change laws of stress and strain of the spindle were studied.It provides a theoretical basis for high-speed motorized spin-dle structure design and optimization.
