THE FUNNEL STRUCTURE FOR THE ANTI-VIBRATION IN SHIP

摘要

The present invention provides a funnel structure for avoiding the resonance of a vessel, which is characterized to change the natural frequency of a funnel by installing a tank divided into multiple partitions in the funnel of a vessel and changing the mass of the funnel through filling the tank with water. Through the present invention, vibration problems can be solved regardless of the changes in the length of a funnel according to an enlargement trend of a vessel. In addition, vibration reinforcement can be accurately performed after checking the real sailing not in a design stage but in a test sailing stage. In other words, when excessive vibration of a funnel occurs due to resonance in a real sailing state, the moment when the vibration of the funnel is extinguished can be found by properly filling water into each partition of the tank immediately at the local site. In this process, neither special limitations in time nor significant costs occur.
