背景：液体污染物通过减少鞋与地板的摩擦而导致滑倒事故。鞋-地板界面中的流体压力减少了表面之间的接触，从而减少了表面之间的摩擦。然而，测量流体压力的技术差距阻碍了对影响这些压力的因素的进一步了解。目的：本研究旨在介绍一种测量鞋下流体压力的技术，并通过量化两种不同鞋的踏面深度和流体粘度对流体压力的影响来证明该技术的实用性。嵌入在地板表面的流体压力传感器用于测量流体压力，而机器人滑动测试仪在地板表面上穿过鞋。收集多个扫描以开发鞋表面上的2D流体压力图。两种鞋的胎面类型（运动鞋和工作鞋），两种流体（高粘度稀释甘油和低粘度洗涤剂溶液），和三个胎面深度（全胎面，半胎面，没有胎面）进行了测试，而流体压力measured.Results：Untreaded鞋结合高粘度流体导致高流体压力，而踩鞋或低粘度流体导致低流体压力。增加的流体压力，观察到的untreaded鞋是一致的摩擦学理论和证据从人类slippingstudy.CONCLUSIONS：这里描述的方法成功地测量流体压力，并产生与摩擦学理论和人类滑动实验的结果一致。这种方法提供了显着的潜力，在评估防滑胎面设计和确定更换鞋的磨损极限。
BACKGROUND: Fluid contaminants cause slipping accidents by reducing shoe-floor friction. Fluid pressures in the shoe-floor interface reduce contact between the surfaces and, thus, reduce friction between the surfaces. A technological gap for measuring fluid pressures, however, has impeded improved understanding of what factors influence these pressures.PURPOSE: This study aimed to introduce a technique for measuring fluid pressures under the shoe and to demonstrate the utility of the technique by quantifying the effects of tread depth and fluid viscosity on fluid pressures for two different shoes.METHODS: A fluid pressure sensor embedded in the floor surface was used to measure fluid pressures, while a robotic slip-tester traversed the shoe over the floor surface. Multiple scans were collected to develop 2D fluid pressure maps across the shoe surface. Two shoe tread types (an athletic shoe and a work shoe), two fluids (high-viscosity diluted glycerol and a low-viscosity detergent solution), and three tread depths (full tread, half tread, and no tread) were tested, while fluid pressures were measured.RESULTS: Untreaded shoes combined with a high-viscosity fluid resulted in high fluid pressures, while treaded shoes or low-viscosity fluids resulted in low fluid pressures. The increased fluid pressures that were observed for the untreaded shoes are consistent with tribology theory and evidence from human slipping studies.CONCLUSIONS: The methods described here successfully measured fluid pressures and yielded results consistent with tribological theory and human slipping experiments. This approach offers significant potential in evaluating the slip-resistance of tread designs and determining wear limits for replacing shoes.
