Slip Distance as an Objective Criterion to Determine the Dominant Parameter between Static and Dynamic Cofs

Abstract

Dynamic friction seems to be more appropriate as a measure of floor slipperiness. However, static friction has been more commonly used and has been a good measure for non-slippery conditions. Therefore, an experiment was conducted to find the dominant COF (static or dynamic) in non-slippery floors and correlating slip distance with each COF. As a result, slip distance was found to be a good measure to represent floor slipperiness because it was exponentially related with static and dynamic COFs. In conclusion, static COF can be a good parameter in non-slippery conditions for prevention of slips and falls.
