Description
Technical field
The present invention relates to the arrangement methods that a kind of ship hull surface outside plate indulges bone.
Background technology
Currently, on ship hull surface outside plate indulge bone arrangement method mainstream there are two types of：Straight-line method and polygometry.Existing
In technology, as shown in Figure 1, Figure 2, Figure 3 and Figure 4, Fig. 1 is to be obtained with the plane cutting hull vertical with captain at the middle part of hull
Cross section, straight-line method is and the plane cutting hull to form an angle with horizontal plane with perpendicular to hull midship section, this is flat
The intersection in face and ship hull plate 2 ', also known as outside plate indulge bone path line 11 ', molded line of the vertical bone path line 11 ' of outside plate in hull frame
It is projected as straight line on figure, outside plate indulges bone 1 ' and arranges along the straight line.Polygometry is the extension of straight-line method, with two or two with
On perpendicular to midship section, and from horizontal plane at the plane cutting hull of different angles, these planes and ship hull plate 2 '
Intersection projects into broken line form on the molded lines of hull frame.Straight-line method is relatively more suitable for outside plate flat region or curvature becomes
Change little region, for the head and the tail region that Curvature change is larger, then must use polygometry.
Although the outside plate that straight-line method or polygometry obtain indulges bone path line 11 ', the projection on the molded lines of hull frame
It is straightway, but this does not imply that outside plate indulges the web 12 ' of bone 1 ' also in the plane of above-mentioned cutting hull.This is because
In the molded lines of hull frame, the intersection point that bone path line 11 ' is indulged from outside plate costal line 21 ' and outside plate makees the outside plate costal line
21 ' tangent line, the angle of cut which indulges bone path line 11 ' with outside plate not necessarily meet synergetic structure specification (i.e.：HCSR specifications)
Requirement not less than 75 °, the web 12 ' that outside plate indulges bone 1 ' can not possibly indulge bone path line 11 ' in the same plane with outside plate.Arrangement
When outside plate indulges bone 1 ', one of starting point is to keep web 12 ' and the outside plate costal line 21 ' of position at a right angle as possible.Straight line
The shortcomings that method is that use scope is narrow；The shortcomings that polygometry is：1 ' bending part of bone is indulged in outside plate, because front and back two sections of outside plates indulge bone
1 ' windup-degree is different, causes front and back two sections of outside plates to indulge bone 1 ' and is mutually staggered at break, generates scissors phenomenon.If front and back two
Section outside plate indulges bone 1 ' when the relative torsion angle on two strong frames adjacent with knuckle point is greater than or equal to 15 °, to avoid
This two sections of outside plates indulge bone 1 ' web 12 ' and panel intersection it is long, then it is front and back to connect that a set square need to be arranged at break
Two sections of outside plates indulge bone 1 '.If outside plate indulge bone 1 ' be more than there are multiple relative torsion angles on two adjacent strong frames or
The case where equal to 15 °, the then set square of respective numbers need to set.Increase the set square that these connection outside plates indulge bone 1 ', drop
The low production efficiency of shipyard.Moreover these set squares need to put certain surplus when manufacturing, and mowing is matched in fact again when assembled in situ,
Therefore a large amount of scene is increased again and matches workload in fact, and construction worker has strong comments.
In addition, when indulging bone 1 ' using straight-line method or polygometry arrangement outside plate, the outside plate on outside plate costal line 21 ' is indulged between bone 1 '
It is unequal away from (21 ' side of a ship of outside plate costal line that two outside plates are indulged between bone 1 ' is long).According to synergetic structure specification, considers outside plate and indulge bone
1 ' intensity there are two important technology index, one be web 12 ' the area of section, the other is outside plate indulges the section mould of bone 1 '
Number, it is proportional that the two indexs indulge 1 ' spacing of bone with outside plate.Therefore, Strength co-mputation is being done to the vertical bone of certain root outside plate 1 '
When, the calculating spacing that spacing maximum indulges bone 1 ' as the outside plate should be selected, seek the value of above-mentioned two technical indicator, and with it is quasi-
The actual value that outside plate indulges bone 1 ' is selected to be compared, to judge whether to meet code requirement.Due to needing to choose when Strength co-mputation
Outside plate indulges the maximum value of 1 ' spacing of bone, and therefore, the outside plate of selection indulges 1 ' size of bone in closely spaced position, and intensity redundancy is excessive,
It is not economical enough, the dead weight of hull is also increased, correspondingly cargo dead-weight is also small.
