Abstract—

The bag-type molecular spring vibration isolator combines the characteristics of air spring and molecular spring. The molecular spring is placed in the bag-type vibration isolator. When the isolator is subjected to external load, the bag-type molecular spring vibration isolator is compressed, and the water invades and escapes from the hydrophobic micropores of the molecular spring material under external pressure, realizing the storage and release of energy. Combined with the deformation analysis of the bladder and the process of water molecules invading the hydrophobic micropores, the mechanical model of the molecular spring isolator was established and the force-displacement relationship of the isolator was deduced. The mechanical model was verified by quasi-static test and the influence factors of vibration isolator performance were analyzed by numerical simulation and experiments.Finally, the vibration isolation performance of the molecular spring isolator is measured by the vibration level drop. The results show that the theoretical and experimental results are in good agreement. The molecular spring isolator exhibits high-low-high segmental stiffness characteristics, and the stiffness in stage II is greatly reduced compared with stage I and stage III. The vibration level drop of the molecular spring isolator is more than 23 dB, and more than 93% of the vibration is isolated.
