碩士 === 大葉大學 === 工業工程與科技管理學系 === 97 === In this paper, the direction of the research is to develop orthoses in principal joints of lower limbs to substitute the gypsum. The paper is appling the optimization technique and manufacture methed of fixed and adjustable-type for orthoses in principal joints of lower limbs design and development. We mainly use the orthoses in principal joints of lower limbs of the mechanical behavior analysis, the impact of modal analysis, the best of design, component shape and size, process parameters, manufacturing entities and experimental measurements etc area to study. The orthoses with a light weight, high permeability, high impact resistance qualities to improve on the weight of protective gear, hot or skin allergy caused by discomfort, inconvenience and other disadvantages. So that when patients use the orthoses can feel comfortable and to lighten the burden, and which manufacturing activities in style and the adjustable fixed adjustable knee orthoses from arthritis and cruciate ligament injuries to patients wearing rehabilitation, restoration of the effect of good effect. In this paper, the best method is to use particle swarm optimization algorithm to find the best protective gear Composites manufacturing process parameters; Manufacturing methods is use of hand-plot method and the resin transfer molding, we use of glass fibers and resin or carbon fiber prepreg materials to create a variety of lower extremity joint brace and using of ANSYS software to analysis orthoses of static and dynamic impact resistance. At the same time, we use experimental and theoretical analysis to verify the correctness of the best design. Finally, we do the durability of orthoses and patients’ survey for designe to amend the most comfortable protective gear in order to achieve (a) fixed effects (b) the effect of air permeability (c) adjusted to facilitate (d) the wearing of safety, comfort and so on.
