Paper Title:
Simulation and Experiment on the Vibration Performance of Pre-Loaded Multi-Plies Bellows
  Abstract

As major equipment for damping and sound insulation, bellows are used as flexible joint and elastic element in the pipeline system of naval ships. In this paper, Finite Element Method was adopted to analyze the static and dynamic performance of bellows. Fourply bellows model was built, which 0~1.2MPa pressure is loaded. Then the stress, vibrating type and frequency of bellows were gotten. The result of simulation shows that the frequency of bellows increases linearly with the increase of pre-loaded. New equipment was produced to test the vibration performance of bellows. The vibration performance of fourply bellows was researched. The frequency, stiffness and damping of bellows were gotten. Some rules were summarized. The result of experiment shows that the frequency and stiffness of bellows increase with the increase of hydraulic pressure. In addition, while the hydraulic pressure is less than 0.8MPa, the damping of bellows increases with the increase of hydraulic pressure. While the hydraulic pressure is more than 0.8MPa, the damping decreases with the increase of hydraulic pressure.
