风帽结构设计优化模型的建立

Optimized Design of Hood Structure

通过测量头部和颈部在各种活动状态下各部位的尺寸,分析出符合头部、颈部活动变化需求的风帽各结构(如帽长、帽宽)的参数.根据参数绘制出两片型风帽结构,经过与人体数据的比较分析得出,两片型风帽在合体性和美观性上都有所欠缺,而分割型风帽则比较合体.同时,通过SPSS软件的多元线性回归分析得出分割型风帽小片量与头围长及帽长的数学模型,进而以人体头围长及帽长的尺寸得到最优化的分割型风帽.

This research is to optimize the hood structure through measurement the sizes of the head and neck at all kinds of activity state, getting the parameters of the structure of hood, such as the length and the width of hood, which accord with the movement of the head and neck. According to the parameters and by com- parison and analysis with human body data, it can be drawn the two- piece hood is not good in fitness and aesthetics and three-piece hood is more fitted structure. A mathematical model about the relationship between the width of the middle piece with the head circumference and hood length can be got with the multiple linear re- gression in SPSS, so that the optimal three- piece hood can be got just with head circumference and hood length. The result shows that the three-piece hood made by this method is the optimal hood structure.
