Problems solved by technology

[0003] The equipment for measuring fabric flexibility parameters based on physics is expensive, and the physical parameters tested are used in physics-based fabric simulation modeling, and cannot be directly applied to fabric geometric simulation modeling
However, when these measured physical parameters are used in the physics-based fabric simulation method, many implicit dynamic equations need to be solved at each time step, and the calculation efficiency is low.

Abstract

The invention discloses a method for generating a fabric simulation model on the basis of geometrical measurement, which comprises the following steps of: selecting a common garment fabric sample; carrying out material measurement of geometric attributes on the basis a fabric; carrying out geometric constraint deformation simulation on the basis of the fabric; carrying out geometric simulation verification on the basis of the fabric. The embodiment of the invention is implemented; the method obtains corresponding characteristic parameters which express the overhang characteristic of the fabric by directly measuring the real fabric sample, is directly applied to geometric simulation of the fabric and overcomes the defects of complex system and high cost on the basis of the physical KES-FB (Kawabata Evaluation System Fabric) and the like.

Description

technical field [0001] The invention relates to the technical field of fabric simulation, in particular to a method for generating a fabric simulation model based on geometric measurement. Background technique [0002] Currently, some physical testing methods have been proposed to measure the simulated flexibility parameters of fabrics. Textile engineering researchers directly use expensive testing equipment, such as KES-FB system (Kawabata Evaluation System), FAST system (Fabric Assurance by Simple Testing), FAMOUS[3] (Fabric automatic measurement and optimization universal system) and ITT (Instron Tensile Tester) to determine and describe the physical parameters of fabrics, pay too much attention to the characteristics of the fabric itself, and emphasize the influence of fabric structure and material properties on fabric simulation. [0003] The equipment for measuring fabric flexibility parameters based on physics is expensive, and the measured physical parameters are us...
