Abstract
The invention discloses a ship noise reduction device. The ship noise reduction device is characterized by comprising a carrying board 1, a hollow damping mass block 2, a sound absorption material 3 and a band board 4. The hollow damping mass block 2 is installed on the carrying board 1. The middle portion of the carrying board is broken and the hollow damping mass block is fixed to the position between the two parts of the carrying board. The band board 4 is fixed to the hollow damping mass block 2. The sound absorption material 3 is installed on the band board 4. By the adoption of the ship noise reduction device, vibration and sound radiation in an engine compartment section of a ship are effectively reduced, the benefit ratio is high, economic cost is saved, the quality is guaranteed, and the production yield is increased.
Description
Technical field
The present invention relates to technical field of ships, particularly a kind of boats and ships noise-decreasing device.
Background technology
Between prior art centre board, the concrete control measure of noise problem are mainly still the conventional methods such as sound absorption, flexible vibration isolation, do not have great innovation.
Summary of the invention
For the problems referred to above, technical problem to be solved by this invention be to provide a kind of simple in structure, tackle boats and ships noise-decreasing device bad, guaranteed quality.
A kind of boats and ships noise-decreasing device, it is characterized in that: comprise supporting plate 1, hollow resistance shake mass 2, sound-absorbing material 3 and band plate 4, the described hollow resistance mass 2 that shakes is arranged on supporting plate 1, separated in described supporting plate, and the described hollow resistance mass that shakes is fixed in the middle of two blocks of supporting plates; Described band plate 4 is fixed on hollow resistance and shakes on mass 2, and described sound-absorbing material 3 is arranged on band plate 4.
Advantage of the present invention:
The present invention effectively reduces vibration and the acoustic radiation of ship power cabin section, has higher benefit ratio, has saved financial cost, and guaranteed quality improves and produces yield.
Brief description of the drawings
Below in conjunction with drawings and the embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further explained.
A kind of boats and ships noise-decreasing device, it is characterized in that: comprise supporting plate 1, hollow resistance shake mass 2, sound-absorbing material 3 and band plate 4, the described hollow resistance mass 2 that shakes is arranged on supporting plate 1, separated in described supporting plate, and the described hollow resistance mass that shakes is fixed in the middle of two blocks of supporting plates; Described band plate 4 is fixed on hollow resistance and shakes on mass 2, and described sound-absorbing material 3 is arranged on band plate 4.
Sound-absorbing material 3 is cruel for gathering ammonia, reach more than 85% at 10-3K frequency band average sound absorption coefficient, hollow resistance is shaken mass 2 for high shear modulus, high desnity metal material, hollow resistance is shaken 8-10 that mass 2 sectional dimensions are about supporting plate thickness doubly, the hollow resistance mass that shakes weighs 2 amounts and should be greater than under same cross-sectional parameter solid resistance 60 of mass 2 gross weights of shaking, and supporting plate 1 is plate floor.
Foregoing, is only preferred embodiment of the present invention, and not for limiting embodiment of the present invention, those skilled in the art are according to design of the present invention, and the appropriate adaptation of having done or amendment, all should be within protection scope of the present invention.
