摘　　要：使用ANSYS中的电磁-热-结构耦合模块并通过中频感应加热正交试验对HSK热装刀柄的感应加热性能进行分析,分别得到刀柄理论感应加热最优温度及刀柄实际感应加热最优温度;以热循环过程中的温度为热载荷,分别使用ANSYS中的热-应力耦合模块以及Coffin-Manson公式,得到热装刀柄热疲劳方式与热疲劳寿命。采用热疲劳试验对预估热疲劳寿命进行了验证,指出适当选取保温时间可延长热疲劳寿命。The induction heating performance of HSK shrink toolholder was analyzed, and the opti- mal temperature of HSK shrink toolholder was gained by using electromagnetism--thermal--struc- ture FEA in ANSYS software and making induction heating experiments respectively. The tempera- ture was regarded as thermal load, the way of thermal fatigue and the thermal fatigue life were ana- lyzed by using thermal- stress with ANSYS software and Coffin--Manson formula the thermal fa- tigue and the fatigue life were also analyzed. At last, the thermal fatigue was identified by experiments and the life can be increased through choosing suitable time of heat preservation.
