Pressure testing of sports bras based on 3D simulation
摘要
Abstract
Garment pressure is one of the key indicators for evaluating the wearing comfort of sports bras.In recent years,the development of 3D simulation technology has provided new methods for garment pressure testing,namely,obtaining virtual pressure by simulating the pressure distribution of garments on the human body through computer software.However,the accuracy of virtual pressure values remains to be validated,particularly for tight-fitting garments like sports bras,which have stringent comfort requirements. To investigate the accuracy of virtual pressure value simulations for sports bras,subjects and virtual mannequins in Style 3D simulation software were used as objects of study.Under four tightness states(normal shoulder straps and back hooks,tightened shoulder straps and normal back hooks,normal shoulder straps and tightened back hooks,and tightened shoulder straps and back hooks),real and virtual pressure values at 17 measurement points while wearing sports bras were measured and compared.Three major conclusions were drawn.First,the pressure analysis diagrams of the virtual mannequin can accurately reflect the main pressure areas on the human body in wearing a sports bra,including the breast area,side area,shoulder area,and underbust area.As the softness of the mannequin's chest increases,the breast area aligns better with the sports bra,while the measured pressure values decrease accordingly.Second,adjusting chest softness significantly improves the accuracy of pressure measurements in the breast area compared to the rigid mannequin.Specifically,for the breast area,the pressure measurements of a soft mannequin with a chest stiffness of 3000 Pa are closer to the real values.For the side area,shoulder straps,and underbust area,the pressure measurements of rigid mannequins are closer to the real values,and they are significantly linearly correlated.Through linear regression,actual pressure values can be roughly estimated based on virtual pressure values.Third,the change trends of virtual and actual pressures remain largely consistent under states b,c,and d.Tightening the shoulder straps or back hooks increases the pressure values at all measurement points and reflects the different impacts of shoulder strap and back hook tightness on pressure in various areas.Specifically,tightening the back hooks has a greater impact on pressure at measurement points in the breast and underbust areas,while tightening the shoulder straps has a greater impact on pressure at measurement points in the shoulder strap area. Experimental test results can provide reference for evaluating the pressure comfort of sports bras and offer a basis for realizing virtual fitting of sports bras.Currently,bra cups in virtual software are realized through dart design and dart transfer,which cannot yet replicate the seamless molding process used in actual production.In the future,it is necessary to continuously optimize and upgrade virtual simulation software algorithms and pressure testing algorithms to improve the accuracy of virtual pressure simulation.关键词
