在充滿活力舞台的運動技術和運動工程,工程師們要特別注意到在用具能量的儲存及損失。充氣(和固體)球的恢復係數常是描述球與硬板間相互作用的影響。謹慎的選擇材料、結構、充氣壓力可達到合適的動態特性。在球離開工廠後,材料及結構保持相對一致,但內部壓力留給了收到相關建議的運動員全權處理。有一項研究進行了在過度及不​​足壓力間的關係觀察和在各種程度變形的能量損耗。

ElectroPuls™ E3000 配備了輕量級壓縮板,用來壓縮整顆球。在上述研究中,許多不同類型的球都進行了測試(足球、排球、五人制足球、籃網球、排球、韻律體操),籃球的結果在以下呈現。每顆球循環的在恆定頻率下被壓縮,初始位移為 5 mm 左右的平均幅度水平,然後我們再以​ 5 mm 做循序遞增。此動作與數位編碼器控制在 WaveMatrix™ 動態測試軟體中做了規定。每個球進行三項壓力測試:

  • 「nominal」壓力指的是在球指定範圍中間處
  • Under-pressure 比 nominal 少25%
  • Over-pressure 比 nominal 多25%

力-位移曲線取自每個初始位移的最後週期(第20個)。數值積分負載及卸載曲線的不同指出了在每個壓縮循環的能量損失。此圖示在各個週期顯示了能量損失對於導入到系統的能量比。比較粗的線相對有較高的能量損失。

適當充氣的球(由綠色線條代表)損失最少三個增壓測試能源。充氣不足球的較高能量損失可能歸因於在彎曲和球面變形(環應變)之​​間的相互作用。在高壓下,球基本上是預載的且面板經歷更高範圍的壓力,也許離開了彈性區。就超彈性材料來說,在更高的壓力下失去更多的能量是毫不奇怪的。全球動態壓縮測試在運動用球內部壓力的角色上提供了洞察力。像這樣的靈敏研究有助於量化全世界球的活動狀態,並建議進一步的新領域研究。
