为了更好地理解人体在行走过程中发生打滑的摩擦学机制,采用Mark II止滑试验机,在干路面、水路面、油路面环境条件下研究橡胶、聚氯乙烯和聚氨酯3种聚合物材料分别与常用的大理石、复合木地板和水磨石地板材料配副的滑动摩擦特性.结果表明:干路面条件下,橡胶的摩擦因数最大;湿路面条件下,3种材料的摩擦因数相差不大;油路面条件下,3种材料的摩擦因数都急剧减小到接近于0.在3种影响因素中,路面污染条件对摩擦因数的影响显著,而配副材料对摩擦因数的影响都不显著.

In order to understand the frictional mechanism of slipping in walking,the sliding frictional behaviours of three kinds of polymeric materials of rubber,polyvinyl chloride and polyurethane was studied by Mark II slipmeter under the condition of dry floor,wet floor and oil floor when mated with common floor materials of marble,compound wooden floor and waterstone. The results show that the rubber has the highest friction coefficient under the condition of dry floor. Three kinds of polymeric materials have significant difference in friction coefficient under the condition of wet floor,and their fric-tion coefficient decrease to approximate zero rapidly under the condition of oil floor. Among the three factors,the influence of contamination conditions is significant,but the influence of couple materials are not significant.
