The Heat Performance Analysis of HSK Shrink Toolholder

摘要

The principle of the HSK shrink toolholder is expanding with heat and contracting with cold. The heat performance of HSK is analyzed. Firstly, the induction heating performance is studied by using electromagnetism-thermal-structure FEA in ANSYS software and experiment, the optimal temperature of HSK shrink toolholder is got. Secondly, thermal fatigue and calculation of the fatigue life is analyzed by using thermal-stress in ANSYS software and Coffin-Manson formula. The loads applied on the FEA model are temperature during the cycle of heating and cooling.
