摘要：
A double-layer hydraulic dynamic anti resonance isolator was designed and manufactured based on the principle of dynamic anti resonance to address the issue of low-frequency vibration isolation. A hydraulic power anti resonance isolator model was established, and the factors affecting the isolation performance and frequency of the double-layer hydraulic isolator were studied. A prototype of the hydraulic isolator principle was processed and frequency sweep tests were conducted. The results indicate that the stacking method can significantly affect the position of the second resonance point, thereby affecting the isolation effect. Compared to single frequency dynamic anti resonance isolators, double-layer isolators formed by superposition can significantly improve isolation performance and isolation bandwidth by adjusting parameters. © 2024 Chinese Vibration Engineering Society.
