Virtual simulation system for drawing process experiment based on Unity 3D北大核心CSCD

Virtual reality technology is referred to as VR technology. Virtual simulation experiments are based on VR technology which simulate a real experimental environment in the computer. With the help of necessary simulation hardware and software users can interact and communicate with objects in the virtual environment thereby generating an immersive operating experience. In 2017 the Ministry of Education promulgated the " Notice on the Construction of National Virtual Simulation Experiment Teaching Project" witch clearly pointed out that it is necessary to integrate information technology into the college experimental teaching actively promote the construction of the national virtual simulation experimental teaching project and improve the quality and technical level of experimental teaching. The construction of virtual simulation laboratory can shift the teaching mode from being flat to being three-dimensional and from being professorial to being experiential and students can gain more direct learning experience. At present an undiversified offline teaching model is still adopted in the drawing process experiment which has a certain gap with the new teaching concept of combining information technology and experimental teaching. In order to promote the informationization of the drawing process experiment we design a virtual simulation system of drawing process experiment based on Unity 3D with FA320A type drawing frame as the simulation object. First of all we analyze the actual requirements of the drawing process experiment including being familiar with the role of the drawing frame mechanism and components being familiar with the drive system of the drawing frame and the position and function of the drafting change gear mastering the process flow of drawing production and knowing the relevant knowledge of textile workshop design. Then the overall framework of the system is designed according to the teaching requirements. Three experimental modules are established namely the cognitive module for the drawing frame mechanism the cognitive module for drawing frame drive system and the drawing process experiment module. The three modules are progressive and can guide the students to complete the learning process of the drawing process experiment independently. Based on this modeling software is used to create and optimize models of the drawing frame and workshop followed by virtual scene construction and human-computer interaction design within Unity 3D. On this basis the authors are both the developers and the users of the virtual simulation teaching software so after completing the development of this system this study analyzes the teaching effect of the virtual simulation software based on the experimental data of the students. Through system development and student experimental testing it is found that the system can eliminate safety hazards in experiments and effectively stimulate students motivation for independent learning which increases students experimental opportunities with an average of 2. 46 times. It also helps deepen students understanding of theoretical knowledge improve their performance and shorten experimental time thus enhancing the effectiveness of experimental teaching. The virtual simulation system for drawing process experiment not only meets practical needs by providing students with an experimental platform with realistic simulation effect and rich learning content but is also expandable and adaptable to future developments allowing the developers to conveniently modify and add experimental content at any time and cultivating more high-quality talents with a sense of innovation and creative ability for the society. In addition the system also provides an important reference for the development of virtual experiments of other textile equipment. © 2022 China Silk Association. All rights reserved.

A finite element approach to the modelling of fabric mechanics and its application to virtual fabric design and testing

This work presents a detailed finite element approach for textile fabrics for mechanical analysis and simulation by combining yarn properties, inter-yarn interaction and fabric structures. The fabric geometries are generated using the TexGen geometric modelling schema developed at the University of Nottingham. This geometric model of the fabric is interfaced with a mechanics modelling environment, ABAQUS, to predict its mechanical properties. The major advantages over other approaches are that all issues arising from textile mechanics modelling are considered, physically measured data are used as inputs and the traditional requirement of user intervention during model creation is removed. The developed model and its implementation are validated using the Kawabata Evaluation System for Fabrics on commercial fabrics subjected to variety of external loadings. The presented validation shows good agreement between the simulations utilising the finite element model and the experiments. The modelling approach is used as a virtual fabric design/testing system which allows designers to input yarn details and geometric fabric structures and to predict how the performance of the fabric depends on textile structures and basic material properties. The virtual testing shows that fabric mechanical performance depends in a complex way on structural parameters, geometric data and loading conditions due to the interaction between various deformation mechanisms. The virtual testing also shows that the bending and shear properties are very sensitive to the cross-sectional shape of the yarns, which need to be modelled accordingly in order to obtain good mechanical predictions.

Quality evaluation of the appearance of virtual close-fitting woven garments

The goal of this research was to investigate the quality of the appearance of close-fitting virtual garment with respect to textile materials’ mechanical (tensile, bending, shear and surface) properties. During the research, the panel of experienced experts was rating visual quality of virtual dresses which were simulated with the help of Modaris 3D Fit (Lectra) software. The objects of the investigations were 100% cotton and cotton-blended woven fabrics. Mechanical properties were defined by Kawabata Measurement System, main part of which is based on uniaxial testing. Mannequin of standard size 164–92–96 was covered with close-fitting virtual dress. The fit evaluation of virtual garment was performed on the basis of local tensile strains at 11 points in warp, weft and bias directions. Simulation results of close-fitted garment showed that mechanical characteristics of selected materials effect strain distribution and the quality of garment appearance. It was defined that tensile properties (tensile strain and tensile energy) of textile materials in weft direction had the strongest effect.
