本研究採用電腦數值分析技術評估運動鞋之力學特性,此項分析
技術可替代實際開發樣品的測試工作,其優點包括:降低材料開發成
本、減少人力成本、減少依據經驗判斷之誤差。本研究透過電腦雕刻
技術建置鞋子之有限元素模型,對於受測者之間施加足底壓力來模擬
個體化的受試者狀況,並且考慮不同步態時期間鞋子與地面之間的角
度關係,透過此項技術能更進一步了解鞋大底與地板實際接觸面積與
防滑性能的結果。
由本研究結果發現球鞋在乾燥地板條件下,鞋大底條紋紋路設計
的結構會影響球鞋的防滑性能表現,當條紋寬度越大時能得到更好的
地板防滑反作用力,而由結果可推得此一現象與鞋底和地面實際接觸
面積的大小有極大關聯性,當鞋底與地面接觸時實際截面積越大,地
板給予的防滑反作用力越大,就成本和時間而言,此計算過程比機械
測試更有效,並且可以在產品開發的早期設計階段為製鞋業帶來明顯
的好處。
The research uses computer numerical analysis technology to evaluate the
mechanical characteristics of human feet and sports shoes. This analysis
technology can replace the testing of developing samples. Its advantages
include reducing material development costs, lowering labor costs, and
minimizing the error based on human experience. Assessing the relevant
indicators of sports shoes is essential to quantify the functions of sports
shoes, such as anti-skid performance, shock absorption performance and
resilience performance. In the highly competitive footwear market these
days, computer numerical analysis technology has become a solution to
accelerating product development and providing customized products.
This technology built a state-of-the-art finite element model (FE) of shoes
through computer engraving technology. Pressure is applied to the sole of
the subjects to simulate the individualized condition, and the angles
between shoes and the ground in different gait situations are taken into
consideration. Through this technology a better understanding of the
correlation between the amount of contact surface of the shoe outsoles to
the ground and the anti-slip performance could be gained.
The results show that, on the dry ground, the structure of the sole tread
design affects the anti-slip performance of the shoes; the wider the tread
grooves, the more the anti-slip reaction. The results demonstrate that this
phenomenon is highly correlated to the amount of contact area between the
outsole and the ground; the more the contact area, the more the anti-slip
counter force from the ground.
In terms of cost and time, this calculation process is more efficient than
mechanical testing. It can also bring about significant benefits to the shoe
industry in the early design stage of product development.
