| Due to various factors acquired,such as different living habits and occupations,a large proportion of people have some parts of their bodies that have variation and present special body types such as humpback,protruding belly and large chest.In our daily life,it is difficult to find two identical body types.There are obvious differences in the body shape characteristics of women in different age groups,especially with the increase of age,the body accumulates more and more fat,resulting in a wide range of body shapes for the middle-aged and the elderly.It is the so-called fit that is perfect,and the person who wears the clothes fits or not knows best.A survey from the market and consumers found that with the continuous development of the economy and the times,people’s purchasing power for clothing has been increasing.However,it was found that the middle-aged and elderly people are not satisfied with the fit and comfort of clothing.In order to enable consumers of all ages and different body types to choose suitable clothing,various clothing enterprises are gradually subdividing the clothing sizes.After consulting,researching and analyzing the research situation of Chinese and foreign women’s fitting women’s dresses,this article finally regards the establishment and analysis of the basic pattern of the middle-aged and old-aged large chest body and chest body as the subject of this research.After the research object is locked,the experiment,detection,research and comparison are carried out through the four parts of anthropometry and data preprocessing,analysis and classification of the body shape characteristics of the middle-aged and old-aged large chest body,construction of a special body shape platform for the middle-aged and old-aged large chest body,and establishment and analysis of a basic sample plate for the middle-aged and old-aged large chest body.The main contents are as follows:(1)74 effective templates were obtained from 110 middle-aged and elderly people through screening of large breasts and elimination of abnormal values.Through correlation,one-way variance and correlation analysis of measurement data of 12 measurement items and 16 derived variables,two individual classification indexes of thoracic transverse sagittal diameter ratio and lumbar type with large dispersion degree are obtained.(2)Taking a certain standard as the basis for body shape classification has certain limitations and is not reasonable.It is difficult to accurately reflect the body shapecharacteristics of middle-aged and elderly women.Therefore,in this paper,the large chest body of the middle-aged and old people is identified by combining the two body characteristic indexes of chest transverse sagittal diameter ratio and waist shape with the lateral shape,and finally the large chest body of the middle-aged and old people is subdivided into 12 types of body types,8 of which are the main body types.(3)In order to construct the human table accurately and effectively,this paper uses K-Means clustering analysis method to obtain the chest and abdomen elevation data of 8kinds of special body,and carries out the human table correction experiment according to these data,and obtains 8 kinds of corrected special body human table through the determination of chest and abdomen elevation data for many times.(4)On the basis of the newly constructed 8 kinds of special-shaped mannequins,8kinds of special-shaped basic garment body templates are vertically cut,and the displacement variation of the main key points in the templates is finally obtained through fitting,correcting and analyzing the mannequins.On the basis of the above research,we have a more in-depth understanding of the body shape of middle-aged and elderly people with large breasts,and have made new attempts and explorations for the following research on the division of the body structure of large breasts.At the same time,it can provide ideas and find research methods for similar projects in a wider range of research.Through the relevant research,with the continuous refinement and deepening of the structural body type classification standards;This also provides support for downstream garment development and design,plate making,production and marketing.There are 21 pictures,41 tables and 63 references. |
