dcterms.abstractAn active-passive dynamic vibration absorber with acceleration feedback is proposed to minimize the impulse response of a single degree-of-freedom (SDOF) system. It has been proved that the proposed hybrid vibration absorber provides better suppression of the impulse response of a single degree-of-freedom system than the traditional passive vibration absorber. The design parameters are the feedback gain, the tuning frequency ratio, the damping ratio and the mass ratio of the absorber. The effects of these parameters on the vibration absorption of the primary structure are analysed based on the analytical model. Design parameters of both passive and active elements of the HVA are optimized for minimizing the impulse response of the primary system. The proposed control system requires only one feedback signal which can be obtained directly using an accelerometer attached onto the primary mass. The control system may be implemented using an analogue circuit connecting an accelerometer, a power amplifier and an inertial actuator mounted onto the primary system. The control system of the proposed hybrid vibration absorber is much simpler than most of the control systems used on active control of vibration absorber found in the relevant literature.-
