Abstract
We have proposed a new Dynamic Absorber Suspension (DAS) and showed a significant effect of the dynamic absorber to suppress the flow-induced sway mode and 2^<nd> torsion mode of head suspension by FEM. In this paper, we redesigned the DAS for practical use. From frequency response function of DAS, we found that magnification factor of sway mode can be reduced to 14dB, and that of 2^<nd> torsion mode is 5dB. Next, we fabricated the DAS based on the analytical result to verify the suppression effect of DAS and measured the frequency response function of a fabricated DAS by changing the damping effect and evaluate DAS design. As a result, we found that the newly developed DAS has remarkable damping effect on the sway mode and 2^<nd> torsion mode.
