Pressure distribution and comfort evaluation of negative-ease yoga pants using ANSYS finite-element simulation

In this study, a virtual simulation model of negative-ease pressure yoga pants was developed and a corresponding human model was constructed to accurately assess pressure comfort when wearing the yoga pants. First, a 3D body scanner was employed to obtain the human body surface. Subsequently, these data were imported into the reverse engineering software Geomagic Wrap to construct the human body model. Then, the assembly of the waist and hip models was completed in SolidWorks by combining the CT images of the female hip joint. Next, the fabric parameters were obtained through by testing the physical properties of the fabric, and these parameters were imported into the finite-element simulation software ANSYS for fitting simulation. Finally, to verify the model’s accuracy, points of the key body dimensions were selected, and the actual pressure was measured by using the AMI3037-SB pressure measurement system (by means of sensors attached to the skin surface). Significance test analysis showed that the significance level between the simulated and measured values was 0.397 ( p > 0.05), indicating that there was no significant difference between the two group. This model applies the research theory of pressure distribution in yoga pants and utilizes the Vidya virtual fitting platform to improve the pattern drafting and fabric improvements for yoga pants, providing a basic research theoretical reference for the subsequent design and market development of tight clothing for the waist and hips.
