Some Aspects Concerning the Behaviour of Friction Materials at Low and Very Low Sliding Speeds
Journal Title: Tribology in Industry - Year 2015, Vol 37, Issue 3
Abstract
The tribological aspects concerning the behaviour of friction materials in the range of low and very low sliding speeds (0.2 – 200 mm/min) are essentially different of those in the high sliding speeds range. This paper aims to study the stick-slip phenomenon which occurs in the range of low and very low speeds. Typically, for the stick-slip phenomenon to occur, the static friction coefficient between the two contact surfaces of the friction materials must be larger than the kinetic friction coefficient. For disc brakes, the stick-slip phenomenon is mentioned in many specialized scientific papers. The phenomenon is manifested through self-induced vibrations. The experimental results were obtained on a dedicated testing machine where the parasite stick-slip motion is reduced through the use of bearings.
