THE REASON FOR FRICTION JUMPS
Keywords:
friction, jump, contacting surfaces, theory of dry friction, the reason for jumps is slip, vibration frequency, elasticity, vibration during metal cutting, contact of rubbing bodies, type of lubricant, rough plane, spring tension, friction force of moving away, harmonic law, displacement, the instant the beginning of a new leapAbstract
This article is devoted to spasmodic displacements of surfaces. Practically observed oscillations have a small frequency. The true cause of the friction jumps is determined. It is established that the friction force from a place is a given increasing function. An analysis of the phenomenon of jumps during friction is considered using the example of a slip of a body relative to a rough plane. After the end of the first jump, the body has uniform motion, then the second jump according to the harmonic law again has uniform motion, etc.
