Study of ice friction has a long history during which several different methods for experimental surface friction coefficient and slidability measurements have been developed. In this article author’s focus on so far rarely discussed possibility of using inclined plane with additional motion detecting sensors, for comparative investigation of how various parameter influence surface slidability on ice. Additional sensors on the side of the inclined plane, combined with data logging and analyzing system, allow to maintain experimental sample sliding time measurements along inclined plane. Time measurements can be used directly or indirectly as sliding velocity, calculated from time measurements and distances between sensors, for comparing how different surface modifications and other parameters affect slidability. If device is equipped with more than two evenly arranged motion sensors it is possible to acquire measurements not only for overall time that is necessary for sample to slide all the way down the plane but it is also optional to analyze sliding time in waypoints in–between overall distance thus offering deeper process analysis possibilities. In experimental part authors give practical examples of how such device can be effectively used for investigating ambient temperature, normal load and surface roughness influence on sample slidability on ice. Description of the device prototype, ice track preparation, slidability experiment settings and surface roughness characterization for examined samples are discussed. Finally graphs that represents ambient temperature, normal load and surface roughness influence on sample slidability on ice are shown and analysis for slidability measurement device usability discussed based on these results.
