Impact friction test method by applying stress wave

Abstract

To understand the dynamic response of two bodies in contact, kinetic friction during impact presently is focused on. A new testing technique, which provides the normal and the tangential impact force independently, is developed by modifying the split Hopkinson pressure bar method. Normal and torsional stress wave propagation in a one-dimensional framework of an axial impact of an input tube on a rotating output tube is analyzed and is experimentally verified. Kinetic friction of brass was clarified at a high rate of sliding up to 5 m/s and is found to be almost constant independent of normal force and sliding velocity. The present technique provides direct measurement of kinetic friction with simple configuration and data analysis.
