Specifically, in this embodiment, after the segment model is constructed, a designer may define a preset welding rule, for example, what welding is used when plates of 10mm and 12mm are butted, and the above example is only convenient to understand, and the designer may actually define the welding rule by himself according to the needs of the designer. If the segmented models accord with the preset welding rules, all the segmented models which accord with the welding rules can automatically create the welding models, so that batch welding seam information input is realized, the welding seam information comprises relevant information needed for calculating the volume information of the welding seam models, such as welding types, groove types and the like, and the time consumption caused by single-piece input is effectively solved.

The method scientifically estimates the welding quantity by combining the segmented model and the welding line information through software, is convenient and quick, and has small error. And the weld joint model of the segmented model which accords with the preset welding rule is automatically established, so that the similar segmented model is prevented from repeatedly inputting weld joint information.
A second embodiment of the present invention is an optimized embodiment of the first embodiment, and as shown in fig. 2, compared with the first embodiment, the present embodiment has the main improvements that, when the segment model does not meet the preset welding rule, the obtaining of the weld information, and the generating of the weld model according to the segment model and the weld information specifically includes:
if the segmented model does not accord with the preset welding rule and the segmented model is a plate, performing boundary division on parts in the segmented model to determine part boundaries;
forming a welding seam track according to the part boundary, and calculating the length of the welding seam;
acquiring weld joint information, adding the weld joint information to a weld joint track, and generating a weld joint model according to the length of the weld joint, wherein the attribute information of the weld joint model comprises the physical quantity information;
further comprising:
if the segmented model does not accord with the preset welding rule and the segmented model is a sectional material, extracting a sectional material assembly curve and taking the assembly curve as a welding seam track;
calculating the length of a welding seam through a section assembly curve;
acquiring weld joint information, adding the weld joint information to a weld joint track, and generating a weld joint model according to the length of the weld joint, wherein the attribute information of the weld joint model comprises the physical quantity information;
further comprising:
if the segmented model does not accord with the preset welding rule, the segmented model is a section bar, and the model attribute of the segmented structure tree containing the segmented model comprises the welding seam information and the welding seam length, the welding seam information and the welding seam length are obtained through the segmented structure tree;
and generating a weld joint model by combining the length of the weld joint according to the segmented model and the weld joint information, wherein the attribute information of the weld joint model comprises the physical quantity information.
Specifically, in this embodiment, when the segmented model is a plate, in the three-dimensional design software module, the boundaries of the plate structural member are described by NSPLINE spline curves, and one plate is described by one spline curve. The efficiency of realizing the spline curve by manpower for rationalizing and segmenting is very low and cannot be accepted by designers. And (3) acquiring interpolation description points of the spline curve through program development, judging the continuity of the first derivative of the curve at the interpolation points, and if the first derivative of the curve at a certain point is suddenly changed, judging that the point is the top point of two edges of the part, thereby determining each edge of the part. The process flow is as in figure 3. Copying the part boundary which is divided through program development, and giving the obtained welding information (welding type, groove parameter and the like) to the welding seam according to different attributes so as to generate a welding seam model.
The length of the welding seam is calculated by a curve fitting technology, and the existing curve fitting technology comprises a broken line fitting method and an arc fitting method. The method using straight lines as element fitting curves can only show the trend of the curves as a whole and cannot well approach the actual form of the curves; the fitting method using the circular arc as the element can not only show the trend of the curve, but also well approach the original form of the curve. The more popular fitting methods are: three-point co-circle method, least square method, double circular arc method. Application analysis: the three-point co-circularity method is an original method for fitting circular arcs, the fitting accuracy of the three-point co-circularity method depends on the positions of three nodes on a curve, the curvature is different, the density degree of the nodes is different, the fitting accuracy difference is large, and the actual application is few. The least square method is complex in calculation, an over-determined equation needs to be solved, and the programming calculation consumes more time, has large calculation amount and low fitting efficiency. Although the double-arc method is high in precision, the double-arc method is large in calculation parameters, large in calculation amount and low in fitting efficiency, and is rarely popularized and applied in general engineering application. The solution is as follows: through the research of a large number of curve fitting methods, a curve equal-arc-length arc fitting method which uses the contour curvature length equal to the arc length, determines the position of the circle center according to the curvature change rule of a curve segment, replaces a convex curve with a convex arc, simplifies an transcendental trigonometric equation by using series expansion and avoids the trouble of iterative solution is provided. The basic idea of the curve equal arc length circular arc fitting method is as follows: for the known curve, a section of circular arc with the arc length equal to the length of the original curve and the convex-concave direction consistent with the original curve is used for approximating and fitting the original curve. In order to ensure that the arc with equal arc length can be highly approximate to the curve, the arc with equal arc length should be controlled within a quarter of the circumference. The following are obtained through statistics: k = chord length/arc length = sin α/α, and curve fitting is satisfactory for engineering applications when 0.9< k < 1. The arc with the same arc length passes through two end points of a curve to be simulated on the curve and is a section of arc consistent with the convex-concave direction of the curve. Therefore, there is no error at the two end points, the maximum error occurs in the middle part of the curve segment, and in order to express the fitting deviation between the actual curve and the arc with equal arc length, the difference between the distance from a certain point on the curve to the center of the arc with equal arc length and the radius of the arc with equal arc length is taken to express. After the allowable fitting error is given, if the actual deviation is larger than the allowable error, two points can be further reduced to ensure the error, and the engineering application requirement is met.
When the segmental model is a sectional material, extracting a sectional material assembly curve as a welding seam, calculating the length of the welding seam, and then
And acquiring the weld information, and adding the weld information to the weld to generate a weld model. The extracted profile assembly curve uses the profile bus acquisition and length calculation technology, and in design software, a profile entity comprises an edge curve and an envelope surface which form the entity. The line-surface entities contain the required curves with the section bar bus characteristics, on the basis, entities with the sub-record names 2304 and the attribute names D000 and-4360, namely the non-uniform rational B-spline curves with the bus characteristics, are obtained through program development, and then the curve length is calculated through the non-uniform rational B-spline pointers. In order to obtain the curve length, a genln function is developed by using a bottom development tool and is used for obtaining the curve length, and a specific implementation flow is shown in fig. 4. In addition, when the segmented model is a profile and there is a segmented structure tree including model attributes of the segmented model, weld information may be acquired through the segmented structure tree, thereby generating a weld model.
According to the invention, different technologies are respectively adopted to generate the welding seam model according to the sectional model, wherein the sectional material can directly obtain the welding seam information from the sectional structure tree containing the model attribute of the sectional model, so that the welding seam model is generated.
The third embodiment of the present invention is an optimized embodiment of the first embodiment, and compared with the first embodiment, the present embodiment has the main improvements that,
before acquiring the segmentation model and the welding seam information, the method further comprises the following steps:
constructing a welding basic database, wherein the welding basic database comprises a welding type, a groove type, a welding line enhancement coefficient, deposited metal density, deposited efficiency, a position coefficient, a welding material loss compensation library, a welding working hour sub-library and a working hour compensation sub-library;
the welding material amount statistical method further comprises the following steps:
if the weld joint model cannot be generated, adjusting the error-reported weld joint information or the segmented model, and regenerating the weld joint model according to the adjusted weld joint information or the segmented model;
after generating the weld joint model, checking the weld joint model;
if the welding seam model does not conform to the actual situation, adjusting the welding seam information or the segmented model, and updating the welding seam model according to the adjusted welding seam information or the segmented model;

the welding material amount statistical method further comprises the following steps: and establishing a design database according to the segmented model, the welding seam information, the welding seam model and the mass statistical table.
Specifically, in this embodiment, a welding basis database needs to be constructed before the segmented model and the weld information are acquired, the welding basis database includes relevant parameters in a series of computer quantitative processes such as a welding type, a groove type, a weld reinforcement coefficient, a deposited metal density, a deposition efficiency, a position coefficient, a welding material loss compensation library, a welding man-hour compensation library, and the like, and the welding basis database is an existing database but can be expanded and updated according to the needs of designers.
In addition, after the welding seam model is generated according to the segmented model and the welding seam information, the generated welding seam model needs to be checked, and the checking is combined by program self-checking and manual checking of workers, so that the accuracy of the finally generated welding seam model is ensured. The weld joint model inspection is divided into two types, one type is that the input segmented model or weld joint information is wrong, so that the weld joint model cannot be generated, and the segmented model or the weld joint information needs to be acquired again. The other is not in accordance with the actual situation, for example, weld joint information which is not in accordance with the actual situation is input, or a weld joint model which is automatically created in accordance with the welding rule, but part of the segment model or the weld joint information is changed relative to the preset weld joint rule, the segment model or the weld joint information needs to be adjusted, for example, for the welding model which is automatically created in accordance with the preset welding rule, if the segment model or the weld joint information is changed relative to the defined welding rule, the segment model or the weld joint information needs to be adjusted, and the weld joint model is updated.
After the weld model is checked to have no problem, extracting the attribute information of the weld model, and generating a quantity statistical table according to the attribute information, wherein the quantity statistical table comprises but is not limited to weld length statistics, welding material consumption statistics and welding time statistics, and a part quantity calculation method is described below.
The total consumption calculation technology of the welding materials comprises the following steps: because the welding grooves have various forms and various welding methods, the common groove forms are summarized and summarized for calculation according to the practical application condition, and parameterization and automation are realized as much as possible. After repeated calculation and verification, the following groove patterns and welding material consumption calculation formulas are obtained. In order to facilitate the later addition of the welding groove type, the groove section calculation module is designed in an open mode, and the welding seam type can be expanded according to actual requirements.
1) Calculation formula of welding material deposited metal amount
The sectional area of the welding joint is obtained according to the geometric dimension of the groove type of the welding joint, and then the sectional area is multiplied by a welding line enhancement coefficient and the deposited metal density, so that the deposited metal amount of a unit length can be obtained: e = r.r.f
In the formula: e-the amount of deposited metal per unit length of weld (g/m);
r-deposit metal density, r =7.85g/cm 3;
r is the weld reinforcement coefficient which can be determined according to the plate thickness and the welding angle.
F-area of weld section (mm 2).
The weld reinforcement factor is shown in Table 1
TABLE 1 weld reinforcement factor
2) Formula for calculating consumption of welding material
The consumption of the welding material can be obtained according to the length of the welding seam at the appointed working position by the following formula:
W= *e*L*ψ*10-3/η
w in the formula-consumption (Kg) of welding material
e-amount of deposited metal per unit length of weld (g/m)
Eta-efficiency of deposition
Psi-position coefficient
The deposition efficiencies of the various welding methods are shown in Table 2
TABLE 2 deposition efficiency
The position coefficient is shown in Table 3
TABLE 3 position coefficient
The welding working hour statistical technique is as follows:
1) welding man-hour correction factor determination
The welding man-hour correction factor has more influence factors, which approximately comprise welding position correction, process correction, cabin correction, monitoring correction, T-shaped assembly non-900 correction, special steel correction, climate correction, equipment correction, other corrections and the like, the design software is combined with the actual production mode of a company to properly simplify the correction factor, and the correction in the following aspects is mainly considered:
weld station repair table 4
TABLE 4 weld location correction
See Table 5 for the process corrections
TABLE 5 Process modifications
Cabin correction is shown in Table 6
TABLE 6 cabin correction
2) Man-hour determination per unit length
The current welding methods of working hours are roughly as follows: manual welding, carbon dioxide gas shielded welding, submerged arc semi-automatic welding, submerged arc automatic welding and hybrid welding; through statistical findings on past and under-construction ships, two types of welds are currently most commonly used: the system mainly designs the two types of welding. When necessary, the welding time quota base can be expanded.
(1) Carbon dioxide arc welding
Bevelling-free single-side continuous fillet welding (the working hour quota is shown in table 7): the method is based on single-side continuous fillet welding, and adopts derivative to realize welding modes such as double-side continuous fillet welding, single-side intermittent fillet welding, double-side intermittent fillet welding and the like. And multiplying the actual condition by a proportionality coefficient to obtain the derived welding man-hour quota.

TABLE 10X-TYPE CONGROUND WELDING WORK-TIME quota TABLE
Secondly, the statistical method of the welding quantity further comprises the steps of defining a special layer, a color and a line type of the welding line model. At present, in most three-dimensional design software, entity colors are defined through layers, and 254 layers and ten colors are provided in total under the default condition. According to the definition of the universal three-dimensional production design on the ship body speciality, the ship body modeling uses 1-40 layers, the generation of welding seams in the welding production design is established at the joint of two or more structures, and the arrangement condition of the welding seams cannot be observed visually by adopting conventional colors. Therefore, special technical treatment must be carried out on the welding color to complete the welding production design, so that the aim of facilitating the observation of designers is fulfilled. In order to not influence the original definition of the three-dimensional production design on the ship body, the welding line layer is defined on the auxiliary layer by adopting a method consistent with the structural line layer. The welding seam layer is preliminarily defined at 239 layers, and a tool can be provided for a designer to define the welding seam layer. Color is a major factor affecting the visual observation of the designer, and in the case of a model that is displayed in its entirety, a regular color cannot be recognized due to the overlap of other colors. Or the phenomenon that the entity modeled before is covered by the color of the entity modeled after is caused by different precedence orders of the entity modeling. The project adopts the colors of RGB 150, 58 and 244, and the colors meet the design requirements through a plurality of tests. The welding model cannot be visually reflected only by color, and a welding model special line type method is adopted to facilitate the visual reaction model, so that the line type can visually react in different views.
And finally, after the mass statistical table is generated, establishing a design database according to the segmented model, the welding line information, the welding line model and the mass statistical table. The design database is used for supporting the production design process and storing design process data, the data mainly comes from the three-dimensional design platform and is used for later-stage statistics and comparison with actual consumed quantity, and errors are analyzed to obtain correction coefficients so as to enable subsequent quantity estimation to be more accurate. In addition, the design database can interact with a plurality of platforms, so that a better use effect is achieved. The three-dimensional design platform is mainly a software tool for three-dimensional production design of companies, such as: the CADDS5, SPD, CATIAL and the like are the basis for developing the design of companies, are carriers of three-dimensional models and are main data sources for data analysis and chart release. The design management control platform is mainly used for carrying out standard management on design data, establishing detailed management authority, design standard, data flow planning, product cooperative management, task issuing and the like, and is the 'brain' for a company to carry out production design and service implementation. The manufacturing management control platform is mainly responsible for receiving design data issued by a design department, including design charts, processing data, numerical control processing instructions and the like, and is responsible for coordination of an upstream design department and a production and construction department and also is an executor for issuing production design charts to construction units. The design database is used for supporting the production design process and storing design process data, and the data mainly comes from the three-dimensional design platform and is a main data source of the product data release database. The product database stores the data generated in the production design process in a product structured form, and meets the requirements of manufacturing on product data. The design difficulty is that the structure of the database meets the requirements of the engineering database on the rapid release of the product data structure and the requirement of the product data structure centralized management, and has expandability. The engineering database is used for storing manufacturing management information and providing data support for manufacturing management departments. The data structure is similar to that of the publishing database. The welding data analysis middleware mainly realizes data analysis and updating of a welding model in the three-dimensional design platform, issues analysis results to a design database and a design management control platform to realize effective management of data, and stimulates the design management control platform to promote and control the life cycle of a single welding design task. The welding data issuing middleware is mainly used for comparing, counting and outputting the welding quantity and the welding time in the database by calling a data trigger after a control instruction is obtained.
