In this report, we investigate the effectiveness of a nonlinear passive vibration isolator using multiple G-shaped beams. One of the characteristics of the vibration isolator using single G-shaped beam is that the isolation frequency range exists in the frequency range beyond the second natural frequency, so the vibration isolation performance was limited owing to the second natural frequency. In the previous report, we tried to reduce the influence of the second order vibration mode in the low frequency range by introducing an isolator using multiple G-shaped beams. In this study, static and dynamic characteristics of a vibration isolator using multiple G-shaped beams numerically and experimentally.
