The vibration absorber has been effective in vibration control. From the demand of manufacturing structural parts with a deep hole, the design of a turning cutting tool with large length–diameter ratio is presented. An analytical approach of acquiring frequency response of primary structure equipped with typical single-degree-of-freedom vibration absorbers is formulated, and background modes are incorporated with the purpose of achieving an accurate tuning of vibration absorber. Specifically, the three-element type is investigated as the damping element of the vibration absorber embedded in the cutting tool contributes to the stiffness, although it demonstrates medium performance of vibration suppression according to non-dimensional analysis. The experimentally tuned frequency response function of the turning cutting tool with three-element vibration absorber achieves 87.1% reduction on the amplitude of the target mode. Finally, several configurations of internal turning operations are carried out to validate the design of the vibration absorber.

基于三元式减振器的大长径比车削刀具设计

减振器在振动控制方面是有效的。从制造深孔结构件的需求出发，提出一种大长径比车削刀具的设计。提出了典型单自由度减振器主结构频率响应的分析方法，并结合背景模态，实现减振器的精确调谐。具体而言，研究了三元件类型，因为嵌入刀具中的减振器的阻尼元件有助于刚度，尽管根据无量纲分析它表现出中等的振动抑制性​​能。带有三元减振器的车削刀具的实验调谐频率响应函数使目标模态的振幅降低了 87.1%。最后，进行了几种内部车削操作的配置，以验证减振器的设计。
