Abstract

The invention provides a ship mainframe cross brace reinforcement structure and a ship, and relates to the technical field of ship construction. The ship mainframe cross brace reinforcement structureand the ship are designed to solve the problems that existing ship mainframe cross brace reinforcement structures cannot effectively enhance the transverse rigidity of joints of cross braces, correspondingly mainframe vibration cannot be effectively suppressed, and the layout of pipelines and passing of crews are inconvenient. The ship mainframe cross brace reinforcement structure is fixed to cross braces, a longitudinal passage is formed between the ship mainframe cross brace reinforcement structure and a longitudinal bulkhead, the ship mainframe cross brace reinforcement structure includes partial longitudinal bulkheads, and the partial longitudinal bulkheads are fixed to the main structure of the ship. The ship includes a ship body and the ship mainframe cross brace reinforcement structure. According to the ship mainframe cross brace reinforcement structure and the ship, the transverse rigidity of joints of the cross braces can be enhanced, and the technical problems that layout ofthe pipelines and passing of the crews are inconvenient are solved while the vibration of a mainframe is effectively suppressed.

Description

technical field [0001] The invention relates to the technical field of ship building, in particular to a ship main engine transverse brace reinforcement structure and a ship. Background technique [0002] The excitation source of ship vibration is usually related to the excitation force caused by the operation of the main engine, and the main engine of the ship is mostly a diesel engine, so the main engine excitation force is mainly caused by the inertial force generated by the movement of the movable parts and the gas pressure change in the cylinder. These forces and moments acting on the side of the diesel engine and the crankshaft will cause the vibration of the diesel engine frame, which may cause damage to the accessories of the diesel engine, thereby causing local vibrations in the engine room and double bottom tank, and finally lead to increased vibration of the superstructure of the hull, which is greatly reduced. Improve the comfort and maneuverability of the ship. ...
