The purpose of this study was to determine how footwear tread groove parameters influence available friction (COF). Utilizing a whole shoe tester (SATRA STM 603), 3 groove parameters (width, depth and orientation) were evaluated. Groove orientation had 3 levels (parallel, oblique and perpendicular), width had 3 levels (3, 6 and 9 mm) and depth had 3 levels (2, 4 and 6 mm). In total, the COF of 27 shoes, each with a distinct groove combination, was assessed on wet porcelain tile. The 27 groove combinations produced a wide range of COF values (0.080-0.344). Groove orientation had the greatest impact on COF, explaining the greatest variance in observed COF values (ŋ(2) = 0.81). The most slip resistant groove combination was an oblique orientation, with 3 mm width and 2 mm depth. The least slip resistant groove combination was a parallel orientation, with a 6 mm width and 6 mm depth.
本研究的目的是确定鞋类胎面花纹沟参数如何影响有效摩擦力（摩擦系数）。利用整鞋测试仪（SATRA STM 603），对3个花纹沟参数（宽度、深度和方向）进行了评估。花纹沟方向有3个水平（平行、倾斜和垂直），宽度有3个水平（3、6和9毫米），深度有3个水平（2、4和6毫米）。总共在湿瓷砖上评估了27双具有不同花纹沟组合的鞋子的摩擦系数。这27种花纹沟组合产生了广泛的摩擦系数值（0.080 - 0.344）。花纹沟方向对摩擦系数的影响最大，解释了观察到的摩擦系数值中最大的方差（ŋ(2) = 0.81）。防滑性最佳的花纹沟组合是倾斜方向、3毫米宽度和2毫米深度。防滑性最差的花纹沟组合是平行方向、6毫米宽度和6毫米深度。
