Optimization of Hood Structure Design

Through measurement the sizes of the head and neck at all kinds of activity state was obtained. It was analyzed to get 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, two-piece hood was drafted. By comparison 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. The width of the middle piece has a big effect on structure of the three-piece hood. 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 regression in SPSS, so that the optimal three-piece hood can be got just with head circumference and hood length.
