利用数值模拟方法研究了半球头弹体与平纹织物的撞击作用,分析了不同摩擦系数和边界条件时平纹织物的弹道吸能特性.数值模拟结果表明,织物纱线间的摩擦效应对其弹道吸能特性影响相当敏感,增大纱线间的摩擦系数,可以提高织物纱线获得的动能和应变能,增大弹体动能损失量,因此有利于提高织物的抗弹能力.边界条件对弹体动能损失量产生直接影响,当织物四边固定约束时,其弹道吸能特性最佳. 相似文献

An automated method of designing technology for manufacturing fabrics of defined structure was developed. An algorithm was
developed for calculation of fabrics of defined structure in designing the technology, consisting of determining the properties
of the fibres used (tensile and compressive viscoelastic parameters, durability parameters, resistance to wear and repeated
loads, hemicyclic characteristics); determination of the coarse fabric structure phase; calculation of warp and weft tension
during frontal battening based on use of the linear theory of warp thread fibre tension in the “warp roller—dropper” zone
and the weft thread pinch tension based on the linear theory of viscoelasticity; estimation of the loom threading tension
using long-term strength criteria; determination of the maximum possible rotation rate of the main loom shaft; calculation
of breakage of warp and weft threads based on the assigned properties of the fibres. Software was created for designing loom
manufacture. The manufacturing process for production of an important number of fabrics was designed. The basic process parameters
for manufacturing fabrics were determined.

Methods which increase the reliability of the technological process and the reproducibility and quality of the fabrics are proposed for joining the pick to the shed and compacting the weft thread on a shutteless loom. It was shown that these methods of forming cloth can be successfully used in further developing the capabilities of shuttleless looms.Translated from Khimicheskie Volokna, Vol. 25, No. 1, pp. 43–45, January–February, 1993. 相似文献

This paper proposes a novel method for segmentation of weft and warp yarns in multicolour yarn‐dyed fabric images. A multicolour yarn‐dyed fabric is cross‐woven by weft and warp yarns with different colours. When a multispectral imaging system is used to measure the colour of a multicolour yarn‐dyed fabric image, its weft and warp yarns need to be detected before analysing their colours. Detection of interstices between weft and warp yarns is firstly conducted. A modified K‐means clustering approach is then utilised to separate weft and warp yarns. The number of clusters is fixed to 2. The metric to measure the distance between a pixel and the mean of a cluster is the CIELAB colour difference. The initial means are determined by the expected values of fitted Gaussian distributions to CIExyY colour histograms. Experimental results show that the proposed method is promising for the segmentation of weft and warp yarns in multicolour yarn‐dyed fabrics, with an improved segmentation accuracy and much faster processing speed than K‐means clustering in CIEXYZ and CIELAB spaces. 相似文献
