• There are various isolators made of springs or rubber for portable vibrating tools. Most of them, however, have not been always effective in vibration reduction of tools. Even though an isolator consisting of conventional undamped absorbers was introduced, It also proved to be ineffective because of the fluctuation of operating frequency. Consequently, a feedback controller was adapted for keeping a constant operating frequency and, moreover, a compound dynamic absorber was developed. Its absorber consists of several "parallel" nominally undamped absorbers with appropriate dispersion of their natural frequencies. Then the attributes of the compound absorber were analyzed and it was confirmed that a frequency bandwidth of its transmissibility was spread over a wider area than the conventional one's. In the experiments, the excellent performance of compound absorber in reducing vibrations fluctuated at the frequency range of controller was verified.
