The study reported in this paper presents an empirical procedure for evaluating the frictional properties in Hertzian contacts subjected to sinusoidal sliding motion. It utilizes the friction induced lateral vibration of a rod to evaluate the parameters of the frictional function using a gradient search which minimize the error between the analytical response and the friction-induced experimental vibrations. The use of sinusoidal sliding motion at the resonant frequencies of the vibrating rod is found to considerably minimize the effect of external vibrations on the experimental results.
