Description
Technical field
The present invention relates to a kind of Ship Structure threedimensional model preparation method, belong to ship model and its making field.
Background technology
Traditional Ship Structure threedimensional model preparation method a, class is to use irony, wooden or other materials sheet materials, is cut out
Cut, bend, being bonded out Ship Structure threedimensional model, a class is to use fiberglass or similar material, by support auxiliary material or mould
Sizing, brushes, irrigates, is bonded the making for completing Ship Structure threedimensional model.
When Ship's Dimension is larger, when making the larger ship model of reduced scale, the element size of Ship Structure becomes very
It is small, even only several millimeters of length, thickness is less than 1 millimeter, using conventional hulls structure three-dimensional model production method, due to material
The limitation of thickness, intensity and performance, can produce following several deficiencies：1) it is difficult by the Ship Structure portion after diminution according to scaling factor
Part is all shown, and is often deleted and is omitted, and only shows critical piece；2) sheet material, the thickness of component, width distortion；
3) it is the intensity of guarantee hull threedimensional model, outside plate retains excessive, has blocked the internal structure at the positions such as hold, wing tank, bow stern,
Influence observation is used；4) Ship Structure is made up of a series of irregular components, especially the outside plate curvature of hull bow stern
Change greatly, some small-sized or novel ships such as yacht, high performance craft, moulding is complicated, traditional Ship Structure threedimensional model system
Make method and the making of physical model is completed according to two-dimentional drawing setting-out, model has larger error with real ship, and model surface is past
Toward also not smooth enough, aesthetics is influenceed.Correct cognition of several defective effect model users to Ship Structure above.
The content of the invention
A kind of Ship Structure threedimensional model is provided and made the invention aims to solve the problems of the prior art
Method.
The object of the present invention is achieved like this：(1) mathematical model is drawn：
Three-dimensional digital model is set up according to Ship Design drawing, three-dimensional digital model size is carried out according to the ratio after reduced scale
Draw, plate members minimum thickness is less than 0.8 millimeter after reduced scale, takes 0.8 millimeter；Minimum widith is less than 3 millimeters, takes 3 millis
Meter, the component that pillar, common rib etc. are independently supported not against sheet material, exposed part maximum length is limited within 10 centimetres；
(2) configuration shows Model Design：
Determine to need the internal structure position of displaying and displaying area size according to Ship Types, need to cut open Ship Structure
Position, level and the mode opened, using the half-sectional structure of larboard as display structure：To show its hull cross section structure, by hull point
For two parts of bow stern, the ship model more than 1.2 meters, be divided into bow, in, three parts of stern；
By taking bulk freighter as an example, bow outside plate is splitted along flat sideline, and flat outer plates are removed, displaying ship side structure, top side tank knot
Structure and base cabin structure, the first cargo hold remove inner bottom plating and bottom side tank swash plate, displaying cargo hold double bottom structure and base cabin structure,
Remove whole outside plates and part cabin inner bottom plating, bottom pier panel, displaying ship side structure, top margin cabin structure, base cabin structure in stage casing
With cargo hold double bottom structure and bottom pier internal structure, stern section removes designed water line above outside plate, deck sloping portion, bottom in cargo hold
Plate, cargo hold bottom center girder, partial bottom pier panel, displaying ship side structure, deck structure, top margin cabin structure, bottom pier internal structure；
(3) 3D printing：
Threedimensional model is made using technical grade light-cured resin printer, lift height is not higher than 0.2 millimeter, sweep speed
6-10 meter per seconds, raw material use white resin；
(4) post-production：
The threedimensional model of completion is removed into unnecessary support, the threedimensional model that Ship Structure is completed after polishing makes.
Compared with prior art, the beneficial effects of the invention are as follows：1) the Ship Structure threedimensional model that such a method makes with
Real ship similarity is high, and 3D printing formed precision error can reach ± 0.1% × mathematical model length.Can correctly it show
Appearance and modeling, the general arrangement situation of real ship.2) the Ship Structure threedimensional model that such a method makes is to illustrate the important portion of hull
The external structure of position, while illustrating the inside of the key positions such as topside, transverse bulkhead, double bottom, bow stern, top side tank, bottom side tank
Structure, comprehensive, at many levels show Ship Structure, user can be easily completed to each portion structure of ship
It is correct cognitive.3) raw material that the method makes Ship Structure threedimensional model are epoxy resin, and model is light, are easy to carry.4)
The raw material that the method makes Ship Structure threedimensional model are epoxy resin, and human body is not injured, environment is not polluted, whole
Individual manufacturing process meets environmental requirement.5) the method makes the post-production of Ship Structure threedimensional model easily, and surface is smooth, U.S.
See, it is not necessary to additional maintenance expense.The post-processings such as spray painting, dyeing are very convenient, low-cost.
