Computer Modeling On The Mechanical And Physical Property Of Woven Fabric

The article mainly study the prediction and modeling of the woven fabric during the process of textile CAD. The thesis improve and extend the former one ,and it mainly complete two contents ,that is, establishing model and extending.(2)the realization of the computer modeling .At first, on the foundation of the plain-woven fabrics' unit analysis method, the article aims at improving and amplifying the mathematical model about the tensile and tearing strength of plain-woven fabrics and twill fabrics, so as that the mathematical model can be applied in more species .The thesis mainly apply the plain-woven fabrics in twill fabrics; The strength which act on the warp of different species(here, the thesis mainly argue about twill fabrics including 2/1,2/2 and 3/1 twill fabrics) during the process of tearing have been dealt with ,and then get the mathematical models of twill weaves after having analyzed them according to the conclusion about plain-woven fabrics .Analyzing and constructing the models having been built ,we can find the result:2/2 and 3/1 twill fabric have the same tensile model .The article founds a general model base after organizing the tensile strength's mathematical model ,and offer a base for the later computer modeling.Secondly, the thesis realizes the design of the computer simulation software with the tensile and tearing mathematical models. With the establishing mathematical models about the tearing and tensile strength of plain-woven and twill weaves, applying program design language(PDL), we can imitate the development pulling thefabric after programming. The customer can pass the GDI on the interface to input the related fabric structural parameters ,and then get the related tensile and tearing strength ;we also can see the relation between the tensile strength and the various fabric parameters.At last, to confirm those models, many plain-woven and twill samples have been collected. By means of experiment and numerical calculation, the agreement between the calculated results and the experimental data is satisfactorily obtained. This confirms the exact degree of those mathematical models and the use of the system.The thesis is of momentous current significance .By establishing the mathematical relation between the fabric parameters and mechanical and physical function of fabrics, we can simulate the fabric mechanical and physical property, at the same time we can get the index and the approximate reference value of the fabric mechanical and physical function. This provide theoretical foundation for the fabric developing and designing, also shorten the period about product designing.Gao Chuanping (Textile Engineering) Directed by Prof. Wang Liming...
