摘　　要：为了提升Style3D软件中针织物的模拟效果,在该软件内搭建虚拟悬垂场景,结合针织物力学性能测试结果,获取针织物虚拟悬垂图像,利用Matlab获取图像的悬垂数据;采用织物悬垂性测试仪获取织物真实悬垂图像及数据,对比软件所得和实测悬垂图像及数据,并通过主观迭代评价优化虚拟数据;在此基础上,采用最小二乘法对优化后的物理属性参数进行拟合,阐明物理属性偏差校正规律。验证结果表明,该拟合结果可以提升虚拟纬平织物悬垂性指标参数的准确性,提高纬平织物在软件中的仿真还原表现。In order to improve the simulation effect of knitted fabric in Style3 D software,a virtual drape scene was built in the software,and the virtual drape image of knitted fabric was obtained by combining the test results of mechanical properties of knitted fabric,and the drape data of the image was obtained by Matlab.The real drape images and data of fabric were obtained by fabric drape tester.The real drape images and data were compared with those obtained by software,and the virtual data were optimized by subjective iterative evaluation method.On this basis,the least square method was used to fit the optimized physical attribute parameters,and the correction law of physical attribute deviation was clarified.Verification results show that the fitting results can improve the accuracy of drape index parameters of virtual weft flat fabric,and improve the simulation restore performance of virtual weft flat fabric in software.
