摘　　要：作为高速加工的一个重要组成部分,热装工具系统在现代制造业中发挥着越来越重要的作用。热装工具系统采用过盈配合进行联接,刀具与夹头的接触特性对工件的加工精度和质量有很大影响,本文采用数值模拟的方式对热装工具系统的接触特性进行研究,分析了不同参数对接触特性的影响。结果表明:随着过盈量、接触长度、主轴转速、配合直径和夹头壁厚的变化,系统的应力和应变均发生变化,并浅析最佳配合参数。As an important part of high speed machining,shrink fit tool system is playing more and more significant role in modern manufacturing industry.Shrink fit tool system is connected to each other in the light of interference fit,in which tool and chuck contact properties influence significantly on machining accuracy and quality of work piece.By applying numerical simulation,the contact properties of shrink fit tool system was studied,and effect of different parameters on contact properties was discussed.The result showed that：with the change of interference,contact length,spindle speed,connection diameter and wall thickness of chuck,the stress and strain of system also changed.Finally the best fit parameters were analyzed in brief.
