逐步回归中服装结构设计数学模型部位间的影响关系

Influence relationship between clothing structure designing math model positions in stepwise regression

以往传统服装结构设计所采用的数学模型都是一元线性方程,较少采用二元线性方程,由于人体的复杂性,所以数学模型的合格率较低,已不能满足智能化发展的需要。通过C++语言对逐步回归进行计算,提出建立颈围、胸围、腰围、臀围、肩宽、身高6个控制部位与其它31个细部部位间的服装结构设计数学模型。将各体型各部位回归模型结果进行比较,找出部位间的影响关系及影响规律,为智能化服装CAD生产提供技术基础。

The mathematics model used in the past for the traditional clothing structure design was linear equation with one unknown, and two-variable linear equation was seldom adopted. As the complexity of human being＇s body, the pass rate of mathematics model is rather low, failing to meet the development needs of intelligence. This paper, through the calculation of stepwise regression by C ＋ ＋ , proposes to develop clothing structure math models of the relationships between 6 key parts （neck girth, chest girth, waist girth, hip girth, shoulder width and body height） and other 31 parts. The results of regression model of various parts of different types are compared, so as to find out the relationship between the parts and the rule of influence and provide a technical basis for CAD of intelligent clothing.
