Description
Technical field
The utility model relates to electromagnetic energy-saving shock attenuation unit, more particularly, relates to a kind of vibration-proof structure being applied to floating cabin.
Background technology
Along with the raising of world's shipbuilding level, people also day by day improve for the requirement of ship's space traveling comfort.Cabin vibration noise is focus of greatest concern in Ship Vibration noise, because cabin is the place of mankind's daily life on boats and ships, amusement and recreation and work, cabin vibration and noise is extreme influence ship's space traveling comfort not only, damaged human hearing organ, also can cause misoperation because of the interchange between noise jamming staff and make boats and ships there is potential safety hazard simultaneously.Therefore, how to take the more effective measure of control of measure of control vibration damping is carried out to target cabin, noise reduction has very urgent demand.
Current domestic boats and ships mainly contain sound absorption technique, vibration isolation technique and floating cabin technology for the Noise and Vibration Control measure in ship target cabin.Sound absorption technique has lays conveniently, and density is less, light quality, because of sound-absorbing material characteristic to the obvious advantage of special frequency band noise reduction.But in engineering practice, only rely on the weight increasing sound absorption structure to improve acoustically effective not only uneconomical, waste material, and effect neither be very desirable.Vibration isolation technique is generally applied and is installed on hull place with each machinery and equipment.At present, boats and ships passive vibration isolation system mainly contains: single-layer partiting polarization system, double-layer vibration isolating system and buoyant raft shock-resistant system.Single-layer partiting polarization is not suitable for the vibration isolation of slow speed of revolution main equipment; Double-layer vibration isolating has good vibration isolating effect, can avoid the deficiency of single-layer partiting polarization system stability difference, but intermediate mass is excessive again limit the application on boats and ships; Multiple devices are shared an intermediate mass and carries out buoyant raft vibration isolation, multiple devices centralized arrangement, quality each other, greatly reduce the quality of middle raft body, and saved space, make design have greater flexibility, easily meet the requirement of general design, through reasonably design, buoyant raft device can have good vibration isolating effect.The principle in cabin of floating be set up out in ship structure cabin one with around bulkhead structure is non-rigid contacts and have the independent tank cell structure of resilient connection, the components such as its floating floor primarily of cabin, wallboard, top ceiling, smallpox resilient hanger form.Wherein floating floor makes cabin and deck keep Elastic Contact, and rock wool and smallpox resilient hanger make cabin and deck and ship wall resilient connection, just defines floating cabin through assembling.Making whole cabin be in one " floats " among state, thus separates airborne noise, mechanical vibration to desired level, reaches good cushioning performance and sound insulation value.
Although at present shipbuilding industry controls cabin vibration and noise by taking above-mentioned series of measures, also achieving pretty good progress simultaneously, reaching far away people to traveling comfort and international norm to the requirement of security of shipping.On July 1st, 2014, the revised draft of " on ship the noise level rule " ratified by security council of International Maritime Organization (IMO) is formally effective, mean and more harsh requirement is proposed to Ship Vibration noise, this just needs us on existing vibration and noise reducing basis, proposes more how more effective vibration and noise reducing measure.
