考虑主应力方向影响的正交各向异性土体强度

利用材料组构与应力主轴的方向关系,对椭圆型角隅函数进行修正并引入到Mohr-Coulomb准则,建立了一个适用于正交各向异性土体的三维强度准则.通过所建立的准则,推导了考虑主应力轴方向变化影响的土体峰值应力比与中主应力比关系的计算公式,获得了土体峰值内摩擦角随中主应力比及大主应力偏转角的变化特性.通过与不同沉积面角度条件下的三轴试验及空心圆柱扭剪试验结果对比表明,理论公式预测的内摩擦角与试验结果一致.     

基于频谱分析的织物粗糙感

传统研究一般通过测试织物表面的几何粗糙度和摩擦性能来预测粗糙感,而认知科学家发现,栅栏粗糙性的辨别取决于表面纹理波动曲线的谐波成分及纹理间距.为深入揭示织物粗糙感的形成机制,基于织物的表面形貌曲线,计算平均粗糙度,统计不同波动高度下的纹理间距,并采用傅里叶方法提取频域内谐波特征,比较分析这些特征值与粗糙感之间的关系.研究表明,织物的粗糙感差异取决于表面波动曲线频域内谐波的最高峰高度,而粗糙感不仅与平均粗糙度有关,也与表面纹理间距有关.

A New Measurement System for Static and Dynamic Clothing Pressure

This study aims to develop a system and measurement method for investigating the static and dynamic pressure behavior of compression products.The self-designed measurement system,named "cloth-press" ( LLY-56B).is a direct measurement method,which is based on a rigid hemisphere with three pressure sensors distributed on its surface.The static pressure is measured at predetermined press depth,and the dynamic pressure is measured under the processing of fabric 3D deformation.The pressure distributions at the basic three sites are accepted as the measurement results.The measurement results provide much information in the field of compression fabric assesment,and the measurement system can be used in scientic research institutes and factories,contributing to optimize process parameters and quality control of compression garment.     

A Computational Model for the Prediction of Seam Pucker

This paper reports on a computational model established based on discriminant analysis for predicting the occur-rence of seam pucker and advising on the correction of causing variables (e. g. fabric properties) to prevent seam pucker. The model has a self - updating feature, viz. automatically up - dating model parameters to im-prove the reliability of the model as new data becomes available. It has been successfully implemented in a re-cently developed sewability system.     

Effect of Commercial Synthappret BAP Treatment on the Tailorability of Light-Weight Worsted Wool Fabrics

By means of measurement with the FAST instruments, the effect of commercial Synthappret BAP treatment on the tailorability of light-weight wool worsted fabrics has been investigated. It was found that the commercial Synthappret BAP treatment unproved the tailorability of the light-weight wool fabrics mainly by increasing the bending stiffness of the light-weight wool fabrics.     

面料及填料对软垫家具火灾特性影响研究

为了分析不同类型面料及填料对软垫家具火灾特性的影响,在ISO 9705标准小室(3.6 m×2.4 m×2.4 m)内对不同面料和填料的软垫家具进行了全尺寸火灾模拟实验.实验中采用的样品为具有相同外形、尺寸、框架的软垫家具,测量了热释放速率、CO和CO2的生成量、CO生成率等相关的火灾动力学参数,给出了CO/CO2的质量比值、CO的生成率、热释放速率三者之间的关系.研究结果表明:填料在软垫家具火灾中是燃烧的主体,但它对软垫家具火灾特性影响比面料小.
