WebStick-slip phenomenon. In the constructed model, a sticking-sliding phenomenon, which reflects the saw-tooth behavior of the frictional force in time, can become apparent at certain parameters. For the equations set (6-7) there is the solution instability with respect to small perturbations. WebMar 24, 2024 · I am conducting a project on friction looking at the stick/slip phenomena in a similar system to that linked below. I have written the code in order to plot the state space (x against x') given some initial conditions for position and velocity. I would now like to plot a phase portrait to show the general direction of motion in a similar ...
WebThe ‘stick–slip’ phenomenon is a common case of autoexcited vibration caused by successive slipping and sticking at a frictional interface with the following characteristics.. The amplitude ... WebThis stick–slip phenomenon can occur if the coefficient of static friction is much greater than the coefficient of kinetic friction. Bowden and Tabor (1950) suggested that static friction is greater than kinetic friction due to molecular bonding between the surfaces.
WebAug 1, 1979 · Abstract. A mathematical model of the stick-slip phenomenon is presented which is related to the characteristic changes of the friction forces as a function of the slip speed. The model leads to simple differential equations without the necessity of using distribution equations. It can be utilized in a simple way to describe actual friction nodes. WebDec 26, 2012 · Importantly, we find that the stick-slip amplitude Δf (typically in the range 0–2 mN or 0–2 g) or slip length (typically in the range 10–50 μm) need not be large for damage to occur; this finding may be the reason that this phenomenon has not been previously reported, because most biotribometers measure the average friction force and ...
WebMar 4, 2024 · The stick-slip phenomenon is the most severe stage of the torsional oscillations present in most drilling routines. It results in drilling operations inefficiency and damages the drilling equipment. Stick-slip arises from the strong nonlinear interaction between drill strings and borehole formation.
