摘要
设计了一种基于颗粒阻尼的减振刀具,并建立了减振刀杆的力学模型。在减振刀杆空腔内添加颗粒,并进行锤击及切削试验。得到以下结论:(1)刀杆空腔中添加颗粒后,刀杆的减振效果明显;(2)填充率相同时,密度较大的颗粒会产生较好的减振效果;(3)填充率与减振效果有着很大关系,在填充量为70%左右时减振效果最好;(4)刀杆中添加混合颗粒的减振效果很好。
It introduces the design of tool based on particle vibration damping and mechanical model. The holder cavity vibration damping particles are added,and the hammer and cutting test. The experimental test shows：（ 1） ＇After the shank cavity adds particles,damping effects Arbor obvious;（ 2） fill rate is the same,the density of the larger particles produce a better damping effect;（ 3） fill rate and damping effect have a very great relationship,in the filling is about 70% of the best damping effect;（ 4） adding and mixing the particles Arbor damping effect than add only a single particle.
