Embodiment Construction

[0022] The present invention will be described in more detail below in conjunction with the accompanying drawings:

[0023] combine figure 1 and figure 2 , The ship rigid vibration-damping mass composite bulkhead structure of the present invention is composed of a typical bulkhead structure, a vibration-damping mass saw, a vibration-damping mass loop and a structural connection form of impedance mismatch. The anti-vibration mass saw 2 is arranged between each equipment installation area 4 on the bulkhead 3 , and the anti-vibration mass loop 5 is arranged at a rib from the edge of the bulkhead to the pressure-resistant hull 1 . The typical ship bulkhead structure is composed of four parts: bulkhead plate, horizontal plank, stiffener, and installation area on the bulkhead. The rigid anti-vibration mass saw and the anti-vibration mass loop are high shear modulus, high density metal materials. The bulkhead anti-vibration mass saws are arranged so that the multi-stage anti-vibr...

Abstract

The invention provides a vibration isolation mass rigid vibration isolation structure for a bulkhead of a ship. A vibration isolation mass loop is arranged between a pressure hull and the bulkhead, and is arranged at the position, which is a frame away from the pressure hull, on the edge of the bulkhead, and a partition is used for connecting the vibration isolation mass loop and the pressure hull; and the bulkhead is provided with vibration isolation mass saws, and the vibration isolation mass saws are arranged among equipment installation areas on the bulkhead. A rigid vibration isolation mass composite bulkhead structural form for the ships of the invention has the effect of attenuating and isolating the propagation of structural noise well under the condition of increasing the weight of a bulkhead structure as few as possible.

Description

technical field [0001] The invention relates to a vibration isolation structure, in particular to a rigid vibration isolation structure of bulkhead vibration damping mass suitable for power cabin sections of various types of ships. Background technique [0002] Noise is one of the main harmful factors in the cabin environment of ships. In recent years, with the development of the maritime industry and the weapons and equipment of the naval forces, the tonnage, speed and power of the ships have been continuously improved, which has made the cabin noise pollution increasingly serious. Ship noise not only seriously affects the combat capability of ships, but also directly affects the health, life and work efficiency of ship crews. [0003] In recent years, ship cabin noise control technology has been developed to a certain extent, but the current specific control measures for cabin noise problems are still mainly traditional methods such as sound absorption, muffler, flexible ...
