Vibration level induced by the friction of two rough surfaces weakly loaded

This paper presents an experiment to measure the vibration level generated when a light solid slides over dry and rough surface. The experimental set-up is based on linear constant motion with speed range from 1 1000 mm/sec. aim study evolution of as function sliding friction area. Measurements show that logarithmic increasing transient velocity. It also observed two regimes exist for versus apparent contact On one hand proportional area, but other this constant.
