Ключови думи: Terry fabrics, Pile structure, 3D computational model, Fabri

Абстракт: Разработен е изчислителен модел за изследване поведението на тъкан с примкова структура при натиск. Моделът е създаден в CAE-системата ANSYS® Workbench™ и работи по метода на крайните елементи. Описани са междинните етапи при създаване на модела. Показана и анализирана е тъканта при различни стадии на деформиране. Симулационните резултати са сравнени с експериментално получени деформационни криви. Получена е висока степен на съвпадение.

Title: Computational Model for softness assessment of pile fabrics applying the Finite Element Method
Keywords: Terry fabrics, Pile structure, 3D computational model, Fabric testing

Abstract: Computational model for investigation of the behaviour of fabrics with loops under pressure is developed. The model is created in CAE-system for engineering analysis ANSYS® Workbench™ based on Finite Element Method. The intermediate stages in model’s development are described. Displayed and analyzed are the different phases of deformation. Simulation results are compared with experimentally obtained deformation curves. The degree of coincidence is very high.
