Abstract:

The key for optimal designing of a garment lies in understanding the pressure which has been brought about by the garment on the human body. 3-D body scanning instrument is used to scan the morphology of the inside part of the leg 6cm above the ankle, and the relationship between the pressure brought about on the leg by the top of socks and the displacement is investigated using finite element method. In this study, the human body is regarded as an elastomer and the contact between the lower leg and the top part of socks is elastic contact. After using finite element analysis and fitting curves, the pressure-displacement quadratic equation can be obtained. Meanwhile, we divide the lower leg cross section into four equal regions according to the angle, and the area shrinkage of each region under pressure can be calculated. And finally, we analyze the relationship between factors that affect pressure levels, and then obtain a function formula between pressure and impact factors by principal component analysis.
