Abstract: This study used hybrid smart materials, shape memory alloy wire enclosed by shape memory polymer sleeves, to design a tunable vibration absorber for vibration reduction over a frequency range. The superelastic wire was trained into helical spring and sleeved with several layers of shape memory polymer to form the structural part of the absorber. Different electric currents could be employed to control the heating and temperature of the shape memory materials in order to tune the dynamic characteristics of the absorber. A theoretical formulation for the configuration design of this absorber based on the principle of minimum total potential energy was derived. In addition, the experimental results showed that with a control current of 1.6 A the heated vibration absorber could demonstrate a 61.6% change in its first modal frequency. After assembling the absorber onto the main structure, the tunable capacity of the absorber under different control currents was measured. Accordingly, the optimal control curren...

TL;DR: The proposed MRG TVA was found to possess a wider tuning frequency range than the TVA based on other smart material such as magnetorheological elastomer and can be controlled to produce 379% of stiffness change or 115% of tuning frequency under just 200 mT magnetic field.
Abstract: This paper proposes a novel adaptive tunable vibration absorber (TVA) based on a smart material the magnetorheological gel (MRG) to achieve a wide range of tonal vibration suppression on the primary system to protect any connected sensitive device. The vibration suppression performance of the MRG TVA was analyzed by conducting a modal test of the primary system under different magnetic fields. The experiment verified that the proposed MRG TVA can be controlled to produce 379% of stiffness change or 115% of tuning frequency under just 200 mT magnetic field. The proposed MRG TVA was found to possess a wider tuning frequency range than the TVA based on other smart material such as magnetorheological elastomer.
