This study quantified the effect of compression load and duration on the deflection of five separate antifatigue flooring surfaces. Following standardized measurement of A Shore hardness, each sample underwent simulated single-leg stance indentation procedures that differed by compression load (45.3 kg, 90.7 kg, 136.1 kg) and duration (initial = 2.5 s, intermediate = 6.25 s, final = 12.5 s). Vertical deflection was compared across conditions, and the relationship between A Shore hardness and deflection was characterized. When compressed with 45.3 kg, deflection was not influenced by duration, but at 136 kg, deflection differed between durations by up to 15%. The relationship between A Shore hardness and deflection was characterized by a third-order polynomial function (R² > 0.991).

这项研究量化了压缩载荷和持续时间对五个单独的抗疲劳地板表面变形的影响。在对肖氏硬度进行标准化测量之后，每个样品都经过模拟的单腿姿态压痕程序，该程序因压缩负载（45.3 kg，90.7 kg，136.1 kg）和持续时间（初始= 2.5 s，中间= 6.25 s，最终= 12.5 s）而不同。 ）。比较了各种条件下的垂直挠度，并表征了肖氏硬度与挠度之间的关系。当以45.3 kg压缩时，挠度不受持续时间的影响，但在136 kg时，挠度在各个持续时间之间的差异最大为15％。肖氏硬度和挠度之间的关系由三阶多项式函数表征（R ² > 0.991）。
