Abstract:

This paper makes 180 female college students measured to get the relative data of the chest ,and then makes use of fuzzy c-means clustering method to analyze the calculated variable to obtain the location of BP point in the upper longitudinal relative position and lateral position. The text uses the 3-D module of the OptiTex 3D garment CAD technology to make the three-dimensional cutting experiment to get the sample plate under the change of BP position, and analyzes the superposition sample plate to summarize the change rule. The result shows that the BP longitudinal position indicator ratio j main points to 1, 1.12 and 1.24, it can be seen that the BP point mainly lies in the middle and lower position between shoulder peak point and waist node. When the BP point moves down, the shoulder dart increases by the amount of the average transverse 0.6 cm. And the waist dart adds the amount of the average transverse 0.6 cm too. The BP lateral position indicator ratio k main points to 0.9, 1, 1.1, and it can be seen that the BP point mainly close to the body two side. Along with the BP point lateral variation, the shoulder dart and the waist dart move around, but the size of dart basically remain unchanged.
