Abstract  Human step friction means the intermittent friction between foot and floor during people's walking, which directly affects people's walking safety. Slipping or falling may occur if the friction coefficient between foot and floor is too small. In order to sufficiently master the characteristics and law of human step friction, research progress was presented in terms of measuring apparatus, influence factors, wear principle and application field. Moreover, it was suggested that more efforts should be made on the research of human step friction on the condition of moving floor. The main testers applied to human step friction included Brungraber Mark II and biomechanical force plate. The main influencing factors were materials of friction couple, floor conditions, format and height of heels, movement parameters, groove of shoe sole and so on. The dominating wear forms were abrasive wear and fatigue wear. The human step friction was mainly applied to the fields of medical recovery, sports training, decoration and shoe making． The result shows that the mechnism of step friction should be researched sufficiently because that whether a person will slip during walking is decided and the quality of human life is influenced by the character of his (or her) step friction.

Key words： human step friction      measuring apparatus      influence factor      wear principle      application field

人体步进摩擦的研究现状

人体步进摩擦是指在行走过程中,人脚与地面之间产生的间歇性摩擦现象.此摩擦现象直接关系到人体在行走过程中的安全性,如果脚与地之间的摩擦系数太小,人体就会发生打滑甚至摔倒.为了充分掌握人体步进摩擦的特性和规律,从原理、测量仪器、影响因素、磨损机理和应用领域四方面阐述了人体步进摩擦的研究现状,指出今后研究的重点应放在路面运动条件下人体步进摩擦的研究上.人体步进摩擦的主要测量仪器有Brungraber Mark Ⅱ测试仪和生物力学测力台两种,主要影响因素包括配副材料、路面条件、行走时所穿鞋子的鞋跟形式与高度、人体行走时的运动参数和鞋底花纹等,主要磨损形式是磨粒磨损和疲劳磨损,主要应用于医疗康复、体育训练、装饰和制鞋等领域.步进摩擦特性决定着人体在行走过程中是否会发生滑摔事故，影响着人类生活和生命质量，因此，有必要对其机理进行充分的研究.
