| Purpose The idea is based on the usage of dynamic vibration absorber for simultaneous reduction of oscillations and energy recovery. The analyzed system consists of two main components: an oscillator (damped part) and a pendulum (tuned mass damper). The rotatory harvester device is mounted in the pendulum’s hanging. The main goal of this investigation is to achieve simultaneous mitigation of vibration and energy harvesting. To improve the effectiveness of the vibration suppression and harvesting effects, an adaptive suspension is proposed. It consists of a combination of semiactive damper (magnetor- heological) together with a nonlinear spring made from a shape memory alloy. Methods This paper presents a numerical and experimental analysis of a vibration absorber/harvester system. The continu- ation and Runge–Kutta methods have been utilized to gain the numerical solutions. The experimental tests were performed on an specially prepared experimental rig. The effects of amplitudes, frequencies, recovered power, and semiactive suspen- sion were studied. Results The obtained results showed that the recovered energy in the vibration mitigation conditions is about 7 mW, while in the unstable region is three times greater. The adaptive suspension can also be applied to reduce unstable regions which occur close to the main resonance and are usually unwanted. Conclusions The study gives an answer to the effectiveness of energy harvesting from the pendulum vibration absorber and suggests that the proposed concept can be useful in practice. |
