摘要

摘要:重型数控立式车床的底座是保证机床稳定性和精度的核心部件之一。针对机床转速提高引起的底座热集中问题，为探明机床转速提高对底座热场和散热的影响，依据传热学和流固耦合力学建立了重型立式车床底座的对流换热数学模型和流固耦合热场模型。通过对重型数控立式车床的底座热场模型进行数值模拟，揭示了机床底座的热传递规律，探明了转速对底座热场和换热强度的作用。流固耦合数值模拟结果与数学模型结果对比结果表明两者基本吻合，为重型数控车床底座的设计和分析提供了有价值的理论依据。

Abstract

Abstract:The base of heavy-duty CNC vertical lathe is one of the core components to ensure stability and precision of the lathe. Aiming to the issue of heat concentration internal structure of lathe-base

to verify the influence that velocity increasing impacts on heat generate and heat dissipation

convection mathematical model and FSI (fluid-solid interaction) heat transfer model of the base of heavy vertical lathe was established according to heat transfer theory and fluid solid interaction theory. The results of numerical simulation of heat transfer model of the base reveal the heat transfer regularity and the influence of velocity that impacts on thermal field

heat dissipation intensity of the base. Comparison result between FSI numerical simulation results and mathematical model results show that they are basically consistent. It provides a valuable theoretical basis for heavy duty CNC vertical lathe design and analysis.
