This paper calculates equation of motion about antiresonance, and describes an analysis result and an experiment result. Two-degree-of-freedom equivalent system which added the mass-spring system to a primary vibration system shows antiresonance, when a mass ratio and a spring constant ratio are made equal. When ratios of mass ratio and spring constant ratio of two-degree-of-freedom equivalent system are 1, the analytical results of which the interval of two angular frequencies of right and left of the antiresonant point was obtained the square root of mass ratio. This dynamic vibration absorber is an easy mechanism and is effective as passive vibration isolation countermeasures. Vibration transmissibilities of antiresonance measured experimentally. The results show good agreement with calculated ones.
