Atomic-scale friction control by vibration using friction force microscope
Manipulation of friction at the nanoscale has been traditionally approached by chemical means (lubrication). Recent friction force microscopy (FFM) experiments demonstrated that it can be done mechanically by applying vibration to accessible elements of the system. This paper provides analytic understanding on why vibration can reduce friction based on a 1D model imitating the FFM tip moving on...
متن کاملEstimation of Tire-Road Friction by Tire Rotational Vibration Model
Tire-road friction is the most important piece of information used by active safety systems. However, most conventional friction estimation/ detection methods are accurate only within the non-linear region. In addition, such methods require numerous sensors, such as yaw rate sensors, acceleration sensors, and steering angle sensors. In this paper, a friction estimation method using a tire vibra...
متن کاملEffects of Vibration on a Coulomb Friction System
Deformable systems that rely on dry friction for their proper functioning are widely found in many engineering applications such as bolted components, railway ballast. The design of these systems is usually considered from static point of view and employing Coulomb model of friction. This paper studies the effects of dynamic loading on the behavior of a two dimensional system by finite element ...
متن کاملThe Vibration and Stability of a Friction-guided, Translating String
Eyelets, capstans and cylindrical surfaces are often used in thread, fiber and paper handling machinery to guide the axially moving element. In addition to providing positional control, these “guides” introduce dry friction forces that alter the vibration and stability characteristics of the system. This paper examines the lateral response of a string that slides through an elastically supporte...
متن کاملDistributed friction damping of travelling wave vibration in rods.
A ring damper can be affixed to a rotating base structure such as a gear, an automotive brake rotor or a gas turbine's labyrinth air seal. Depending on the frequency range, wavenumber and level of preload, vibration of the base structure can be effectively and passively attenuated by friction that develops along the interface between it and the damper. The assembly is modelled as two rods that ...
