Problems solved by technology
[0002] As the ship is under the influence of complex and frequent external loads for a long time during the voyage, the hatch corner structure of the hull is also affected, and is always in a state of high and low stress alternating, resulting in cracks and structural damage.
[0003] During the entire service process of the river-sea direct ship, it has been affected by alternating loads from the river section and the sea section for a long time, so that the corner structure is always in a state of high and low stress alternating, which makes the hull corner structure very prone to cracks and structural damage.

The invention provides a hatch corner structure of a river-sea direct ship, which includes a corner base body and a crack initiation suppression area, a composite area, a crack resistance groove and a surface extension area arranged on the corner base body; wherein, the corner base body It has an arc-shaped side, and has a fan-shaped block on the arc-shaped side; the crack initiation suppression zone is integrally formed in the fan-shaped block of the corner base; the composite zone includes a plurality of first Groove; the crack resistance groove area includes arc-shaped crack resistance grooves arranged along the arc length direction of the crack initiation inhibition zone, and the crack resistance groove area is connected with the crack initiation inhibition area; and the surface extension area includes a plurality of The second groove, the surface extension area is connected to the side of the crack resistance groove area away from the crack initiation inhibition area. The invention can effectively improve the fatigue performance of the hatch corner of the river-sea direct ship, prolong its fatigue life and improve the fatigue reliability of the river-sea direct ship.
Description
technical field [0001] The invention belongs to the technical field of ships and marine engineering, and particularly relates to a hatch corner structure of a river-sea direct ship. Background technique [0002] Due to the complex and frequent external loads affecting the ship for a long time during the voyage, the hull hatch corner structure is also affected, and it is always in a state of alternating high and low stress, which makes it extremely prone to cracks and structural damage. [0003] During the entire service process of the river-sea direct ship, it has been affected by alternating loads from the river section and the sea section for a long time, so that the corner structure is always in a state of alternating high and low stress, which makes the corner structure of the hull easy to crack and cause structural damage. Phenomenon. As the accumulation of fatigue damage intensifies, it will seriously affect the service life of the hull structure. Therefore, it is par...
