Abstract
The inward displacement perpendicular to the human body produced by external pressure is a key point to evaluate the pressure comfort and optimize the design of compression garment. However, it is hard to obtain the accurate displacement value using the existing instrument and equipment. In order to find a simple and feasible method to obtain displacement data after the human body wearing compression clothing, the waist cross-section model of human body was obtained by computerized tomography scanning and Mimics modeling, and then the displacement distribution was simulated after wearing four sample elastic pantyhose (A1, A2, B1, B2) using finite element method in this article. Finally, the functional relationship between pressure/displacement ratio and angle was obtained through quadratic curve fitting. Research indicated that the four fitting curves showed almost the same tendency, and we can approximate that the functional relationship between pressure/displacement ratio and angle remains almost unchanged no matter what kind of elastic pantyhose the human body wearing, and no matter what state the human body was in (static or dynamic). As a result, when the human body was under clothing pressure, the corresponding displacement value on the body can be calculated on the premise of the known pressure value at any point of the waist cross section using the quadratic equation. The conclusion provides an important reference for evaluating clothing pressure comfort and optimizing clothing structure. This method is also applicable to other types of compression garment.
