中文摘要 | 本文主要探討不同材質、硬度及厚度之醋酸乙烯鞋墊發泡材對其衝擊緩震性能之影響效應,使用衝擊試驗法進行測試分析,利用量測之加速度峰值來評估其緩衝吸震性能。結果顯示,具橡膠與不具橡膠之醋酸乙烯發泡鞋墊的衝擊緩震能力受材料硬度及厚度顯著的影響,且厚度越厚及硬度越軟其緩衝吸震性能力較佳。就不具橡膠醋酸乙烯發泡材而言,其厚度及硬度的改變對緩震性能的影響是非線性;就具橡膠醋酸乙烯發泡材而言,其厚度的改變對緩震性能的影響是非線性,而硬度的改變對緩震性能的影響是線性的。整體而言,具橡膠之醋酸乙烯發泡鞋墊之衝擊緩衝性能與不具橡膠之醋酸乙烯發泡鞋墊者相當。此一不同材質、厚度及硬度之醋酸乙稀鞋墊材對衝擊緩震性能影響結果,對選擇或設計運動鞋緩衝系統之緩衝吸震性能是相當值得注意的重要因素。 |
英文摘要 | The present study focuses on the assessment of the impact cushioning of various EVA foamed shoesoles with different hardness and thickness. An impact testing method is used to test the cushioning abilities of EVA foams. The peak g score is utilized to evaluate the impact cushioning of EVA foams. The result shows that peak g scores are significantly affected by and decrease as the sole thickness increases and the sole hardness decreases for both EVA foams with or without rubber components. The influence of the foam thickness and hardness on the peak g score is in a nonlinear relation for EVA foams. However, for EVA/Rb foams, the influence of the foam thickness on the peak g score is in a nonlinear relation, but the effect of the foam hardness on the peak g score is in a more linear relation. Generally, the impact cushioning ability of EVA/Rb foams is equivalent to that of EVA foams. It is believed that the effect of material, hardness and thickness of EVA foam on its impact cushioning performance is an important factor for selecting or designing the shoe cushioning system. |
