No.10（2015）13.Design of dynamic vibration absorbers using a 3D printer

Yusuke Iwata, Yasuhiro Nishikawa, Yujiro Abo

  The modeling was conducted on the shape of dynamic vibration absorber (DVA) readily designable with simulation. Utilizing this model, the DVAs were designed based on numerical calculation and manufactured with a 3D printer. The calculated natural frequencies were basically consistent with the resonance frequencies obtained by the vibration test on manufactured DVAs. And several DVAs for cantilevers and vibratory tools were designed and manufactured using this model. These attached DVAs were capable of reducing the targeted vibration.
