By a trial simulation, it was found that the frequency range of vibration reduction due to antiresonance was wider than that of the flam damper by installing several Dynamic Absorbers with similar natural frequencies and adjusting their damping factors. To expand this range to the maximum, we propose a parameter adjustment method for a Multi Dynamic Absorber using the basic theory of Transfer Path Analysis. A diagram showing the relationship between the numbers of installed dynamic dampers, the target value for reducing the vibration amplitude ratio, and the range of vibration reduction frequencies can be derived.
