Abstract

In response to the limited vibration reduction performance of single-layer rubber isolation systems for ship power equipment, a particle damping rubber isolation system is proposed by combining particle damping technology and rubber isolators. A coupled simulation method based on multibody dynamics discrete element (MBD-DEM) was proposed to establish a simulation model of a cantilever beam particle damping vibration reduction system, and experimental verification was carried out. The average error between the simulation and experimental results of the equivalent damping ratio was 7.0%. On this basis, a single-layer particle damping isolation system for ship power equipment was established, and the influence of particle filling rate, size, and material parameters on the isolation performance of the isolation system and its energy dissipation characteristics were studied. The research results indicate that a filling rate of 90% has the best vibration isolation effect; The isolation effect improves with the increase of particle size; When the filling particles are tungsten carbide particles, the vibration isolation effect is the best, and the vibration acceleration level at the resonance frequency is reduced by 7.7dB.
