一种袖笼曲线CAD的优化设计方法

A Kind of Optimization Design Method for Armhole Curve CAD

服装袖笼曲线形状决定着衣袖的造型,是服装美观性和舒适性的一个重要因素。目前服装CAD中袖笼曲线的形成是通过设计师选定一些型值点后,用过型值点的自由曲线完成的,人为经验因素较多。在分析袖笼曲线的特点后,建立了袖笼曲线的数学模型,构造了一种样条曲线描述袖笼曲线,无需经验确定袖笼前后拐点位置,达到袖笼曲线的自动生成,实现了袖笼曲线的完整设计,只需输入一些必要的参数,便可输出圆顺美观并满足经验的袖笼曲线,在服装CAD及服装设计方面有广泛的应用。

The shape of costume armhole curve decide sleeve sculpt, is an important factor of costume aesthetic property and comfort. Now in garment CAD, the armhole curve was shaped by designer to choose some model value points, and was completed by using these model value points to form free-form curve, it has some contrived sense datum. By analysis the characteristic of armhole curve, a kind of sample strip curve for description armhole curve was constructed in this paper, armhole curve can be automatically created, the integrity design of armhole curve can be realized, this method have a wide application in garment CAD and garment design.
