Abstract

The floor slipperiness is an essential property for the pedestrian safety. This study was conducted to develop the slip test apparatus to be well accorded with actual characteristics of human gait; and the correlation between RCOF (Required coefficient of friction), Rz (Surface roughness), and 3 coefficients of slip resistance (C.S.R (Coefficient of slip resistance), BPN (British pendulum number), and SCOF (Static coefficient of friction)) were analyzed. Result of the analysis revealed that the cadence, stride length, and step length were proportional to the walking speed, and the significant correlation between walking speed and RCOF was found. However, the correlation between RCOF and the other respective coefficients of slip resistance was almost unidentified thus it would be difficult to identify the actual property of floor slipperiness with the RCOF alone.

바닥의 미끄럼 저항은 보행자 안전을 위해 반드시 필요한 성능이다. 본 연구는 실제 인간의 미끄럼과 잘 대응하는 미끄럼 시험장치를 개발하기 위한 기초적 연구로서, 지면 마찰력(RCOF)과 표면 거칠기(Rz) 및 3가지 미끄럼 저항계수(C.S.R, BPN, SCOF) 간의 상관성을 분석하였다. 보행 속도가 증가할수록 보간 거리, 보폭, 분당 보행 수 모두 증가하며, 보행 속도와 RCOF 간에는 유의한 상관성이 있었다. 그러나 RCOF와 각 미끄럼 저항계수 간에는 상관성이 거의 없기 때문에 RCOF만으로는 바닥의 미끄럼 저항 특성을 파악하기 힘들다.
