傑出硏 O u R e p r o — 教 f a of e d 用功能測試與電腦仿真技術輔助設計 運動鞋與便鞋 Designing A t h l e t ic and Casual Footwear Based on funct ional Testing and Computer Simulation 體 育運動科學系洪友廉敎授領導的研究 隊伍，獲本地數家製鞋公司和創新及 科技基金資助，以及自動化與計算機輔助工 程學系協助，開發了新穎的設計技術。該技 術包括三個部分：電腦仿真、鞋動態功能 測試，以及足部特徵數據庫。電腦仿真技術 可從人類腳形數據、鞋料性能數據和鞋功能 測試數據，推斷運動時腳、鞋、地的相互作 用與影響。功能測試應用人體運動的科學原 理和研究技術，測試人體從事各種 活動時， 鞋的動態功能特徵，如避震、貼地、穩定、 保護和舒適等性能。足部特徵數據庫可紀錄 不同人種的足部特徵。有了這些新 技術， 香港的造鞋廠商便可設計合乎各地人需要的 鞋和建立自己的品牌。該系已根據研究結 果，為李寧公司提供運動鞋功能測試服務， 協助開發新產品。 With the support of the Innovation and Technology Fund and the local footwear industry, and the collaboration of Department of Automation and Computer-Aided Engineering, Prof. Youlian Hong of the Department of Sports Science and Physical Education led a team to develop a new technology for designing athletic and casual footwear. The new technology consists of three parts: computer simulation, functional testing, and a foot shape database. Computer simulation reveals the intricate relations among the foot, the footwear, and the ground based on foot shape, the mechanical properties of the materials used, and shoes' functional test data. It provides detailed information on how a shoe will function in various circumstances even before it is built. Functional testing is an approach that systematically tests the function of the shoes during various movements, providing dynamic features of shoes, such as cushioning, traction, stability, prevention, and comfort. The foot shape database, which contains foot information of various human races, will help Hong Kong footwear manufacturers design products that best fit customers around the world. The implementation of the research results will also help Hong Kong footwear manufacturers to build their own brands. A service based on this study, involving a sport shoe functional test has been provided to L i Ning Co. for the development of new products.
