Abstract
FIELD: shipbuilding. SUBSTANCE: ceiling is provided with vibration absorbing devices and supports for vibro-active equipment; ceiling is mounted on hull and bulkheads of ship; ceiling has plating and crossing strengthening beams whose ends are supported by knees. Beams are from composite material which consists of alternating stiff layers which take up load and viscoplastic layers; coefficient of loss of oscillatory energy is no less than 0.02. Beams are connected with plating by means of threaded joint through heat-insulating gaskets. Plating is provided with coming over perimeter. Clearances are provided between plating and hull and between plating and bulkheads. beams are secured to knees by means of detachable mechanical joints, threaded joints for example. At loss coefficient of laminated beams no less than 0.1, dampening of vibrations transmitted to ship's hull ranges from 8 to 10 dB in wide band of audio frequencies. EFFECT: enhanced efficiency.
