More Information
Summary:The invention belongs to the technical field of ships and ocean, and particularly relates to a low-noise deck structure device of a main engine room. The invention aims to provide the low-noise deck structure device of the main engine room. The low-noise deck structure device comprises a deck plate, reinforcing ribs, bases and vibration isolation mass loops, wherein the reinforcing ribs are weldedto the back surface of the deck plate, the bases are welded to the front surface of the deck plate, and the closed-loop rectangular vibration isolation mass loops are formed by using hollow square steel broken welding or full welding. The two bases supporting a same device are completely surrounded, and the two bases supporting two devices are provided with the same kind of vibration isolation mass loops to isolate structural vibration waves generated by a power machine. The rectangular square steel loops isolate transmission of structural noise and also ensures that a deck does not generatelarge deformation, so that
