Suppression of friction by mechanical vibrations.
Mechanical vibrations are known to affect frictional sliding and the associated stick-slip patterns causing sometimes a drastic reduction of the friction force. This issue is relevant for applications in nanotribology and to understand earthquake triggering by small dynamic perturbations. We study the dynamics of repulsive particles confined between a horizontally driven top plate and a vertica...
متن کاملVisual Sensor with Resolution Enhancement by Mechanical Vibrations
The resolution limit of visual sensors due to nite pixel spacing can be overcome by applying continuous low-amplitude vibrations to the image|or taking advantage of existing vibrations in the environment, for instance in a mobile robotics application. Thereby, spatial intensity gradients turn into temporal intensity uctuations which can be detected and processed by every pixel independently fro...
متن کاملStability of Granular Materials under Vertical Vibrations
The influence of periodic vibrations on the granular flow of materials is of great interests to scientists and engineers due to both theoretical and practical reasons. In this paper, the stability of a vertically vibrated granular layer is examined by linear stability analysis. This includes two major steps, firstly, the base state at various values of mass holdup (Mt) and energy input (Qt) is ...
متن کاملMechanical detection of carbon nanotube resonator vibrations.
Bending-mode vibrations of carbon nanotube resonators were mechanically detected in air at atmospheric pressure by means of a novel scanning force microscopy method. The fundamental and higher order bending eigenmodes were imaged at up to 3.1 GHz with subnanometer resolution in vibration amplitude. The resonance frequency and the eigenmode shape of multiwall nanotubes are consistent with the el...
متن کاملMechanical vibrations of pendant liquid droplets.
A simple optical deflection technique was used to monitor the vibrations of microlitre pendant droplets of deuterium oxide, formamide, and 1,1,2,2-tetrabromoethane. Droplets of different volumes of each liquid were suspended from the end of a microlitre pipette and vibrated using a small puff of nitrogen gas. A laser was passed through the droplets and the scattered light was collected using a ...
