“…The displacement ratio can be seen as an index of the influence of the tangential compliance on the friction reduction. Equations (18)- (24) can yield the friction force over one steady-state period. The friction ratios r x with the value i = 1 (without a stiction phase) and i = 0 (with a stiction phase) for θ = π/2 (perpendicular vibrations) are plotted in Figs.…”

“…The vibration direction can be either normal [11][12][13][14]16,23,24] or tangential [3,15,[17][18][19][20] with respect to the contact surface. This effect can be used for the reduction of process force in manufacturing processes, such as ultrasonic machining and ultrasonic-vibration drawing [9], or solving the problem of position control in high vacuum environments, such as electron microscopes, where friction can be controlled through the variation of the vibration amplitude only.…”

A reduction of friction by vibrations has been observed in various experiments. This effect can be applied to actively control frictional forces by modulating vibrations. Moreover, common methods of controlling friction rely on lubricants and suitable material combinations. The superimposition of vibrations can further reduce the friction force. This study presents a theoretical approach based on the Dahl friction model that describes the friction reduction observed in the presence of the tangential vibrations at an arbitrary angle. Analysis results indicated that the tangential compliance should be considered in modeling the effect of vibrations in reducing friction. At any vibration angle, the tangential compliance of the contacts reduces the friction reduction effect. The vibrations parallel to the macroscopic velocity are most effective for friction reduction.

“…Tworzydol and Becker studied the influence of forced vibration on static friction coefficient by numerical modeling of the compliant contact interface [9]. They showed that frictional force decreased in vibration condition and explained that the interface damping weakened the friction reduction effects.…”
