砂石颗粒阻尼器的纵振抑制研究
Suppression of Longitudinal Vibration by Sand Particle Dampers
摘要
Abstract
This research investigates the application of sand particle dampers to longitudinal vibration reduction in ship propulsion shafting systems.A simulation model of the sand particle dampers is established using PFC3D software to detect the damper's energy dissipation ability under various parameters.The study focuses on the affect of operational speed,filling ratio,and excitation amplitude on the energy absorption.The simulations indicate that speed and filling ratio significantly im-pact the energy dissipation,while excitation amplitude has a lesser effect.Experimental tests based on these simulations con-firm these findings,and the results are in a good agreement with those of simulations.关键词
