摘　　要：车削振动主动控制中,考虑到车削加工中刀架的受力以及控制执行器的性能特点,刀架设计至关重要。为了减小径向载荷对执行器的作用,本文利用柔性铰链设计了CA6150柔性专用刀架,在此基础上,分析了专用刀架的静、动特性,表明该结构达到设计要求,并通过脉冲激励实验证明了刀架具有较好的动特性,可以满足CA6150车削振动主动控制的要求。Given the tool rest subject to force in turning processing and the characteristics of control actuator,the design for tool rest plays a vital role in turning vibration active control. Using flexure hinge,a special flexible tool rest for CA6150 is designed to reduce the radial loading on the actuator,on the basis of which this paper analyzes the static and dynamic properties of this special tool rest,whereby showing that the structure can meet the design requirements,and then a pulse excitation experiment is conducted to verify that the holder has a better dynamic properties and can meet the requirements of turning active control for CA6150.
