Description
Technical field
The present invention relates to the paper pattern design method in a kind of brassiere production process, particularly a kind of suitable customization is customized or mass customized fit brassiere construction design method.
Background technology
Dobson once pointed out " symbol that pattern tissue is high-tech in the fashionable dress art design ", the status and the complexity of visible apparel pattern design in 1885.Three-dimensional brassiere is echoed at flexible body surface by the fabric with telescopicing performance and forms, has the comfortable fit underwear of body and mind, therefore needs paper pattern design teacher that higher professional knowledge is arranged.Yet, make a general survey of the brassiere manufacturing industry, the brassiere pattern is usually still based on experience, repeatedly the method for sample and producing.Pertinent literature instructs obviously and lacks, and literature search shows that nineteen sixty-eight so far, only have in the world in several the books that relate to the brassiere paper pattern design and also just mention slightly, as Shanghai science tech publishing house, 2004. Shanghai: seal is built honor, Chang Jianliang. underwear paper pattern design principle and skill [M].And the acquisition methods of all these brassiere patterns is not to retouch the back again by quantitatively providing by upright sanction, is exactly to come by reducing the development of chest measurement loose measure on the basis of upper garment prototype.The quantitative principle that it is hidden of giving for each position does not then have concrete description.Therefore, people also are short of relation between brassiere model and human bodily form and understanding very much, so that the production cycle of brassiere and cost increase, and the mistake in the research and development of new product process is many, the time is long, and fitness is poor.
Summary of the invention
In sum, the defective and the brassiere fitness of brassiere plate-making method that how to overcome the existing repetition test that lacks scientific basis and guidance and traditional experience is poor, it is technical problem to be solved by this invention, for this reason, the object of the present invention is to provide a kind of mass customized brassiere construction design method based on necessary variable of female chest and Curves and Surfaces Modeling Technology, be used to improve the scientific rationality and the production efficiency of brassiere paper pattern design, satisfy the science production requirement of customizing with mass customized fit brassiere.
For achieving the above object, the present invention is achieved in that
A kind of mass customized brassiere construction design method based on Curves and Surfaces Modeling Technology, concrete steps are:
1. gather young women chest characteristic parameter sample
Randomly draw age distribution and be research object young schoolgirl 190 people of 18-35 year, valid data are 184 groups, choose 32 the measurement projects and the derivative index that can reflect the female chest morphosis, add height, body weight, amount to 34 and are the sample collection parameter;
2. determine to describe five main factors of female chest with PCA
Utilize SPSS software, above-mentioned acquisition parameter index is carried out principal component analysis and the elementary divisor loading matrix is carried out the rotation of variance maximization quadrature, extract 5 main factors of reflection female chest feature, it is the breast abundance factor, the chest measurement form factor, the thin portion of breast form factor, the breast positioning factor and trunk degree of enclosing changed factor;
3. establish the human body call parameter of mass customized brassiere structural design with relevant function method
Carry out the Pearson came correlation analysis respectively by parameter project, establish and realize the mass customized model design trunk call parameter project of fit brassiere, be specially chest measurement A above-mentioned five main components
2, under bust girth A

4. set up and be suitable for the trunk linear variable displacement regression mathematical model that brassiere is produced in batches
Bodily form data to above-mentioned necessary variable are carried out regression analysis, obtain the linear regression Mathematical Modeling at the brassiere making sheet human body control position that is applicable to batch process, promptly use a small amount of known basic position variable: under bust girth A
3With chest difference E
1Reflect other control position correlated variables;
5. create the fit brassiere structural design of customizing based on Curves and Surfaces Modeling Technology
When design women T is cut apart cup steel ring formula brassiere, structure brassiere surface modeling on people's platform, the conversion method of utilization Curves and Surfaces Modeling Technology and three-dimensional and two dimension and how much are graphing methods directly, and creating with the chest characteristic parameter is the customize step and the formula of model design of the brassiere of independent variable.
The above-mentioned brassiere of on people's platform, the realizing structural design of customizing: realize according to the real human body parameter; If utilize trunk correlated variables linear regression Mathematical Modeling, brassiere to customize during construction design method is extended to mass customized and produces in batches; Cut apart cup steel ring formula brassiere structure design principle with T and instruct other brassiere style structural design.
The technical characterstic of the inventive method is:
1. the inventive method is based on female individual chest shape feature, and the necessary variable of chest shape and the Mathematical Modeling of being established by principal component analysis, correlation analysis and regression analysis are foundation; To obtain the method for designing of personalized brassiere cup seam dart in brassiere cup seam dart parametric technique or the three-dimensional virtual chest form environment based on the breast characteristic parameter; Use Curves and Surfaces Modeling Technology and replacement theory three-dimensional and two dimension, created step and formula that the mass customized model of brassiere designs, set up the corresponding relation between brassiere model parameter and human body parameter with the direct graphing method of two-dimensional geometry.
2. the present invention is the mass customized model method for designing of brassiere of foundation with the necessary variable of female individual chest shape, is different from the traditional repetition test and the method for empirical parameter, and the scientific rationality of new method has solved the technical problem of brassiere fitness difference.
The technique effect of the inventive method is:
Utilize the method, can be based on personalized three-dimensional surface chest characteristic parameter, with Curves and Surfaces Modeling Technology and step and formula three-dimensional and the brassiere structural design that the two-dimensional transformations theory is created, the utilization regression mathematical model, the real individuation bra batch customizing sampling design idea that realizes, filled up the personalized brassiere structural design theory blank, for realizing the design of brassiere CAD model fast and pushed away grade place mat good basis.Scientific design method has improved operating efficiency, has reduced the brassiere manufacturing cost, has solved the pattern technical problem of brassiere fitness difference, has satisfied the production demand of the fit brassiere of customizing.
