超声波振动镗削“刚度化”的研究

STUDY ON THE "RIGIDITY" WITHULTRASONIC VIBRATION BORING

对超声波振动切削镗刀杆的“刚度化”效果进行了较为详细的理论分析及试验研究，揭示了超声波振动切削“刚度化”效果的实质，指出了影响“刚度化”效果的主要参数是速度系数Ｋ＿（ｖｏ）Ｋ＿ｖ越小，“刚度化”效果越显著。

The theoretical analysis and the experimental study for the 'rigidity' effectof ultrasonic vibration boring tool bar is introduced, and the essence of 'rigidity' effectisrevealed. The results have shown that the 'rigidity' effect is mainly influenced by thespeed coefficient Kv, the smallet is Kv the more obvious 'rigidity 'effect.
