摘　　要：HSK热装刀柄是高速数控机床的重要通用部件之一,由于其动静态精度、刚性、可靠性、安全性等直接影响到被加工零件的质量和加工效率,因此从理论上分析各因素对系统刚度的影响有着重要意义。本文基于ABAQUS,运用FEA手段分析了不同的过盈量、夹持量、悬伸量以及转速对HSK热装刀柄—刀具系统径向刚性的影响,通过回归分析手段得到对系统刚度影响最为显著的因素。HSK shrink toolholder is an important part of the high-speed CNC machine tool,and its static accuracy,rigidity,reliability and safety directly affect the quality of the part and machining efficiency. So it is meaningful to analyze how the factors influence the system rigidity. Mainly based on ABAQUS,with the application of the FEA method,the influence of different interference amount,clamping length,overhang length and rotation speed to the system radial rigidity of the HSK shrink toolholder and tooling system is analyzed,and obtained the most significant factor that influence the system rigidity by regression analysis.
