Abstract: The purposes of research are to improve the mathematical model on the multi-dimensional space boundary conditions including clothing pumping effect and the body compositions for each segment across body, and to develop an industry-oriented and user-friendly computer-aided design simulation platform for clothing thermal functional design. The mathematical model investigates the physical mechanisms of the multi-boundary conditions affected by the multi-node human and multi-style clothing, including clothing materials, garment styles and proper fit, and the wearing status on each body segment. An engineering database is developed to support the clothing thermal functional design. By logically organizing various types of information, this database can facilitate the processes of design, analysis, and evaluation. It can also perform the following: analyze the industry requirements for the clothing thermal functional design; build a human model database, including the physical and physiological parameters; establish a textile material database along with the physical, structural parameters and suppliers for all kinds of fiber, yarn and fabrics; and develop an apparel as product database together with the material, structural parameters, styles, clothing patterns, and sewing chart. A visualization software package is developed to visualize the simulation results of clothing thermal function design. It can visualize the biomedical implication according to the psychophysical relationships between the psychological sensory perceptions and thermal stimuli, which are derived from the thermal regulation analysis. The software works by: (i) defining the data structure based on the visualization scheme to support 3D and dynamic animation; (ii) mapping the heat and moisture properties to the 3D human from core layer to skin layer on each segment; and (iii) mapping the heat and moisture properties to the 3D garments covered on the human body on each segment.
Maximizing computer technology, an integrated CAD software system platform for clothing thermal engineering design is also developed. This system guides the user to analyze the logic of clothing thermal function engineering design and biomedical implication processes, from selecting the 3D garment and the 3D human model to defining multi-dimensional space boundary conditions and clothing pumping effect. The system also assigns the thermal design properties to visualize the 3D human and garments. A CAD system with high computation performance improves simulation efficiency and credibility, laying the foundation that allows many users to perform online simulations simultaneously. The developed cloud platform of clusters based on the improved CAD simulation software can improve the simulation speed and accuracy, supporting multi-user online design and simulation. In summary, not only an improved mathematical model for the multi-dimensional space boundary conditions including clothing pumping effect and the body compositions for each segment across body has been proposed in this thesis, but also an integrated CAD software system platform for clothing thermal engineering design has been developed according to rules and solution of the improved mathematical model, which are supported by an engineering database and visualization package.
