Abstract
The invention relates to a ship T-shaped bar through hole linear structure. The ship T-shaped bar through hole linear structure is characterized in that a T-shaped bar through hole is provided with a left-right-symmetry structure; the line type of one single side sequentially includes an elliptical arc, a first arc, a second arc and a straight line which are sequentially connected; the long radius b of the elliptical arc is close to the inner side of the T-shaped bar through hole, and the short radius c of the elliptical arc is close to outer side of the T-shaped bar through hole; the whole T-shaped bar through hole is of an apple shape with the head facing downwardly. The ship T-shaped bar through hole linear structure has the advantages the hole is full and round, the through hole is welded with at least one edge of a T-shaped bar, part of the stress on the free edge of the through hole is transmitted through weld joints from the T-shaped bar, the other part of the stress on the free edge of the through hole is caused by plate deformation, stress testing and analysis prove that by the form of the elliptical arcs, the first arcs, the second arcs and the straight lines, fatigue limit brought by the stress of a plate is long, the theoretical service life of the plate is long, and high design safety is achieved.
Description
Technical field
The present invention relates to a kind of boats and ships T profile through hole linear structure, belong to boats and ships T profile through hole technical field.
Background technology
In the version of boats and ships, the general section bar that adopts, through the form of sheet material, realizes hull rigidity framework, through hole has at least with T profile while be connected with Type of Welding, stress on through hole free margins, a part is passed over by weld seam from section bar, and a part is the stress that sheet deformation causes.As Figure 1-Figure 2.
Maximization along with boats and ships and the requirement to Research of fatigue strength of vessel more and more higher, the through hole of existing T profile is due to the limitation of line style itself, overall perforate is comparatively flat, as shown in figures 3 to 6, the shape of perforate is that circular arc and straight line are combined into, use the form of circular arc-straight line-circular arc-straight line-circular arc, in approximate kidney ellipsoid, it is inadequate that the radius of verge of opening cannot do large opening fairing degree further.Due to above reason, often perforate edge stress is comparatively large and fatigue strength cannot be met, Fig. 4-Fig. 6 illustrates the stress analysis in existing T-shaped hole, and the fatigue limit in Fig. 5 is minimum is only 2.2 years, and therefore existing T profile through hole linear structure design is unfavorable for safety and the serviceable life of boats and ships.
Summary of the invention
The technical issues that need to address of the present invention are: existing boats and ships T profile through hole linear structure, overall perforate is comparatively flat, use the form of circular arc-straight line-circular arc-straight line-circular arc, the radius of verge of opening cannot do large opening fairing degree not further, causes perforate edge stress comparatively greatly and fatigue strength cannot be met.
The present invention is by a kind of new through hole Alignment Design, thus obviously can improve the fatigue strength at through hole edge.Because as apple, we are called apple hole the title of this through hole to shape.
The present invention takes following technical scheme:
A kind of boats and ships T profile through hole linear structure, described T profile through hole has symmetrical linear structure, and one-sided line style is the form of the elliptic arc of smooth connection successively, the first circular arc, the second circular arc, straight line from bottom to top; The major radius b of described elliptic arc is inside T profile through hole, and short radius c is outside T profile through hole; T profile through hole entirety is in head apple form down.
This open bulk is comparatively full mellow and full, through hole has at least with T profile while be connected with Type of Welding, stress on through hole free margins, a part is passed over by weld seam from section bar, and a part is the stress that sheet deformation causes, by stress test and stress analysis, prove the form adopting this ellipse, the first circular arc, the second circular arc, straight line, the fatigue limit that the stress that sheet material is subject to brings is longer, and illustrate that the theoretical life-span of sheet material is longer, design safety is higher.
Further, described elliptic arc distance of center circle equals 39.6-83.7mm from the distance a at T profile through hole center.
Further, the length of the major radius b of described elliptic arc equals 37.8-95.6mm, and the length of corresponding short radius c equals 22.1-58.9mm.
Further, the width H of the T profile panel that described T profile through hole linear structure is corresponding equals 100-250mm.
Beneficial effect of the present invention is:
1) fatigue strength at T-shaped through hole edge is obviously improved.
2) T-shaped through hole edge is mellow and full full, and intensity is higher.
3) the approximate shape of falling apple of T-shaped through hole profile, line style is smoothly attractive in appearance.
4) the theoretical life-span of sheet material is longer, and design safety is higher.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
See Fig. 7-8, a kind of boats and ships T profile through hole linear structure, described T profile through hole has symmetrical linear structure, and one-sided line style is the form of the elliptic arc of smooth connection successively, the first circular arc, the second circular arc, straight line from bottom to top; The major radius b of described elliptic arc is inside T profile through hole, and short radius c is outside T profile through hole; T profile through hole entirety is in head apple form down.
This open bulk is comparatively full mellow and full, through hole has at least with T profile while be connected with Type of Welding, stress on through hole free margins, a part is passed over by weld seam from section bar, and a part is the stress that sheet deformation causes, by stress test and stress analysis, prove the form adopting this ellipse, the first circular arc, the second circular arc, straight line, the fatigue limit that the stress that sheet material is subject to brings is longer, and illustrate that the theoretical life-span of sheet material is longer, design safety is higher.
Following table is the apple hole example (unit: millimeter) under different panels width:
| H | a | b | c |
| 100 | 39.6 | 37.8 | 22.1 |
| 120 | 45.3 | 44.9 | 27.2 |
