| Abstract: | The coefficient of friction is measured during relative oscillation between sliding surfaces. Measurements are made during
regular oscillations in which the excitation has a modulated amplitude, and during chaotic oscillations in which the excitation
amplitude is fixed. The friction force is measured for paper on paper, and titanium on titanium. A friction law is derived
based on observations from the measurements. This friction law is applied to a simulation model of an experimental forced
oscillator. The simulated and experimental oscillators have similar qualitative dynamical features in the phase space. |
