An Investigation Into Clothing Pressure Comfort On 3D Human Body Human Waist Based On Finite-element Analysis

With the concept of healthy dressing deeply rooted in the modern society, consumers in pursuit of fashion are paying more attention to their physical and mental health and comfort after wearing. People requirements of clothing comfort are getting higher and higher, in addition to heat and moisture comfort and feeling comfort, pressure comfort has gradually become one of the key indicators in measuring clothing comfort. In various wearing parts of human body, study of clothing pressure on human waist was rare. The research object of the subject is human waist, on the basis of clothing body engineering, this subject studied the pressure comfort by wearing tight test clothing. By combination of finite-element analysis and objective measurement, and it investigates the comfortable pressure threshold of human waist based on BP neural networks.The subject summarizes the domestic and international relevant research literatures on clothing pressure comfort, overview of the concept of pressure comfort and its factors and impact on human body. First, non-contact three-dimensional body scanner was used to obtain human body point cloud data of experiment subjects and use Geomagic to make up a surface model of human body and use Pro/E to obtain a model of waist section. Then sections were intercepted to model human waist by finite-element method simulating the states variations after the pressure on the waist and determining pressure tested points to do objective pressure experiment.Six females were employed as study subjects. The pressure values of different waistline of tight test clothing were measured by virtual pressure measure system based on Labview. Through data processing of the experiment and the analysis of the results, it reflects back of the waist has higher pressure in the condition of the same specification tight experiment clothing, and it has the representation of the waist compression. Finally, combined with BP neural network data and comfort assessment of individuals to explore human psychology pressure comfort threshold.The study indicates that pressure comfort threshold on human waist is 3.566Kpa. Study subjects claim to be uncomfortable when pressure exceeds 3.758Kpa. Thus, a more scientific and practical evaluation system of pressure comfort for the waist garment can be established, which will provide a reference to optimal design of waist garments.
