Research On The Structure Of Sports Bra Based On 3D Human Body Measurement

Sports bra is one of the functional underwear that directly with the humanskincontact, the size ofpressure and the structur’s reasonable will be affect thehuman comfortdirectly, so the sports bra design should tend to humanity. Because theamount ofsweat movement of the body and severe degree is much higher than the normalstate, therefore the ordinary bra can not meet the requirements of function of the sports brawhile you in motion...In order to make the sports can protect bra breast,absorbentbreathable protection, comfort,function and does not interfere with the exercise, itmust to research frommulti angle breast shape, body movement, fabric, clothingstructure etc.In this paper, we will from the oerspective of the physiological characteristics of breast,morphological features, breast movement, the bra fabrics and styles of angles etc, todesigncan a bra that not only can protect the breast, but also comfortable to wear, movefrelly. By changing the model structure parameters to study the sports bra comfortFirst, Through study of breast physiological structure and morphological charact-eristics，analy breast composition,and rereach the shape of chest,he skin stretching rate, andprovide a theoretical basis for the structure design and the selection of fabric sports bra.Second, though measure the Chest related data of210northwest young women were bythe uncontact laser3D scanne and selected for processing and analysis.find thatthe measurement of basic dimensions of intermediates and distribution range of sample.Factor four can reflect yong female chest chest feature extracted by principal componentanalysis, namely the location factor breast height factor, breastshape factor,breastcircumference factor, breast to find out the effect of the main parameters of bra structuredesign.Third, based on the analysis of3D body measurement data as the basis, determinethe underwear mannequin dimension75B, the size is75B that of bra idesign and paramentsof structural changes of the milk cup bra:long and long dide milk cup. Sudy is combinedwith the target group of the motion and the result of consumer behavior desiged for thistarget group of moderateconsumption without rim light sport bra. Sports bras fabrics todetermine the two aspects of human biomechanics and micro clim-atology based on, andthe fabric elasticity test.Fourth, according to the design of the structure for three-dimensional cutting，get theSports bra bodice prototype. Based on human data analysis results, the bra fabric elastic rateas the basis,correction and scaling sports bra bodice prototype is get sports bra bodiceprototype structure of elastic fabric.Draw a sports bra pattern, and the bra pattern ofrevising the basic pattern in order to achievesatisfactory so far, then change to the basicstructure of the local parameters(milk cup long a–nd side milk cup long) value. Get7sports bra structure of differentstructural parameters anddimensions, and make7bra.Fifth, participants dressed in all kinds of clothes in different rate of movement, throughthe pressure, the breast motion and subjective evaluation on the breast pain to twoconclusions. A, with the increase of rate, participants dressed in all kinds of clothes invarious parts of the pressure value, breast acuteness degree of motion, breast pain notcomfort level increases，and different factors to influence human thermal comfort underdifferent rate. B, the participants dressed in all kinds of clothes at the same rate of movementof human body each place pressure on the value, breast acuteness degree of motion, breastpain because of the different samples. According to the participants subjective feeling fromgood to bad sort generally comply with the laws of parameters.Test wearing kinds of clothing movement at different rates, analysis of displacementbased on the marker point curve and amplitude mean can get three conclusions. A, with therate increasing, the mark point displacement wave increase. In addition to change milk cupside line length, the displacement curve to follow certain rules; B, Point to point about milksternal displacement and milk cup straight long amplitude mean can evaluate the sports braon breast movement process; C, participants wore different samples at three different rateswhen motion, control the degree of breast bra from good to poor sorting uniform kind, aresample G> sample E> sample C> sample A>sample B> sample D> sample F.Comprehensive evaluation results of subjective and objective appearanceand bra ultimatelyconcluded that the best sports bra sample are sample A,sample B, sample E.
