Abstract
The utility model is related to a kind of ship with large hatch openings cabin front bulkhead hatch negative angle corner structure, including transverse bulkhead (1) and longitudinal bulkhead (2) and the negative angle corner (3) positioned at cabin front bulkhead hatch, the negative angle corner is connected in sequence by oval segmental arc (3a), straightway (3b) and arc section (3c).The oval segmental arc is positioned close to the side of longitudinal bulkhead.The scope of the A/F in the negative angle corner is between 800mm~1600mm, and the scope of the radius size of the arc section is between 200mm~500mm, the length range of the straightway is between 100~200mm.The utility model effectively improves the torsional strength and the factor of stress concentration at cabin front bulkhead opening corner, and then improve its fatigue strength, greatly reduce because thickness of slab increase caused by stress concentration, the width spaces of deck perforate have been compressed to minimum in the horizontal simultaneously, the influence passed through to equipment arrangement and personnel is reduced.
Description
Technical field
The utility model is related to the structure design at the opening corner of ship with large hatch openings cabin front bulkhead cabin, specifically refers to, one
Plant ship with large hatch openings cabin front bulkhead hatch negative angle corner structure.
Background technology
With the progressively maximization of ship with large hatch openings (container ship, multi-purpose cargo ship etc.) principal dimensions and loading capacity, cargo hold
A/F accounts for the ratio of ship width near or above 0.9, and at cabin front bulkhead opening corner, the torsion of main deck is strong
Degree and fatigue strength have increasing need for drawing attention.If cabin front bulkhead does not make any transition processing, its structural shape
It is a right angle just as shown in Fig. 1, there is a wedge angle point M, black arrow is Structure stress distribution arrangement.When in hull
Have in the presence of stress, sharp corner point is because there is the presence of stress concentration, and its internal stress level will be higher by perhaps more than surrounding structure
It is many, cross not how long fatigue damage occurs, cause crackle to occur, cause the fatigue rupture of Ship Structure.
In order to reduce or avoid the stress concentration at corner, in traditional design, one can be all designed in cabin front bulkhead
Positive corner, for smoothly transitting for structure, thus can significantly reduce the stress level at corner, it is ensured that the peace of hull
Entirely.But with the appearance of larger-sized vessel, positive corner uses the type of elliptic arc transition shown in circular arc type or Fig. 3 in Fig. 2
Formula not can solve caused by twist warp intensity and stress concentration due to being arranged, using upper constraint
The problem of region thickness of slab is sharply increased.To improve this problem, cut-in type angle (is also known as using a kind of negative angle corner mostly at present
Corner) pattern handle, circular arc pattern as shown in Figure 4 and the elliptic arc pattern shown in Fig. 5, the negative angle corner original better than positive corner
Because as follows, 1. by space utilization in cargo hold due to being limited, circular arc and elliptic arc can not all do too greatly, if making negative angle
Corner pattern, it is possible to further do its big external form, it is possible to reduce stress level herein.2. because negative angle corner is hided in transverse bulkhead
Below so that a part of stress strength has been shared on transverse bulkhead, so as to the stress level at effectively reduction corner.But
With the further maximization of the ship with large hatch openings such as multi-purpose cargo ship and container ship, if it is desired that the corner of cabin front bulkhead exists
Still design to meet the requirement of construction torsion intensity and fatigue strength, the circular arc or ellipse in negative angle corner using conventional negative corner
Arc can be made very big.It is exactly that the floor space of area of aircraft cabins can greatly reduce, shadow that a bad consequence, which can so be brought,
Ring equipment arrangement and personnel pass through.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of ship with large hatch openings cabin front bulkhead hatch negative angle
The transverse opening on deck, while structural strength and fatigue strength is ensured, has been compressed to minimum zone by corner structure.
In order to solve the above problems, the technical solution adopted in the utility model is as follows：
A kind of ship with large hatch openings cabin front bulkhead hatch negative angle corner structure, including transverse bulkhead, longitudinal bulkhead and before cabin
The negative angle corner of end wall hatch, it is characterised in that：
The negative angle corner is connected in sequence by the arc section positioned at the oval segmental arc at top, straightway and positioned at bottom.
The oval segmental arc is positioned close to the side of longitudinal bulkhead.
Further, the opening width range in the negative angle corner is 800mm~1600mm.
The radius size scope of the arc section is 200mm~600mm, the length range of the straightway for 100~
Between 200mm.
Compared with prior art, the beneficial effects of the utility model are：
1st, the torsional strength and the factor of stress concentration being effectively improved at cabin front bulkhead opening corner, largely reduce
Because thickness of slab increase, while the width spaces deck perforate have been compressed to minimum in the horizontal, subtracts caused by stress concentration
Few influence that equipment arrangement and personnel are passed through.
2nd, in real ship design, by two kinds of designs for calculating existing ellipse negative angle corner and the utility model negative angle corner
Scheme, is computed results contrast and shows, conventional elliptical type corner fatigue is unsatisfactory for requiring, and new corner fatigue meets and required.

Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples, the embodiment is not to reality
With the restriction of novel protected scope, it is clear that those of ordinary skill in the art obtain on the premise of being not required to pay creative work
Other embodiment, these belong to protection domain of the present utility model.
With reference to shown in Fig. 6, a kind of ship with large hatch openings cabin front bulkhead hatch negative angle corner structure, including transverse bulkhead 1 and vertical cabin
Wall 2 and the negative angle corner 3 positioned at cabin front bulkhead hatch, the negative angle corner is by positioned at oval segmental arc 3a, the straight line close to longitudinal bulkhead
Section 3b and arc section 3c is connected in sequence.
The oval segmental arc, which is set, to be preferably provided at close to the side of longitudinal bulkhead.
Preferably, the opening width range in the negative angle corner is 800mm~1600mm.
The radius size scope of the arc section is 200mm~500mm, and the length range of the straightway is 100~200
Between.
The utility model is effectively improved torsional strength and the factor of stress concentration at cabin front bulkhead opening corner, very great Cheng
Reduced on degree because thickness of slab increase caused by stress concentration, while the width spaces deck perforate are compressed in the horizontal
Minimum, reduces and equipment is arranged and influence that personnel pass through.
In the design of real ship, by two kinds of design sides for calculating existing ellipse negative angle corner and the utility model negative angle corner
Case, is computed results contrast and shows, conventional elliptical type corner fatigue is unsatisfactory for requiring, and new corner fatigue meets and required.
