This paper presents an overview of an interactive multimedia vibrations program called GT Vibrations. GT Vibrations contains a series of modules that deal with elementary vibrations, transient vibrations, and continuous systems. The program is intended to be used as a supplemental tool for undergraduate courses in vibrations and system dynamics at Georgia Tech. The underlying goal of the progra...
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 ...
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...
3D reconstruction based on laser light projection is a well-known method that generally provides accurate results. However, when this method is used for inspection in uncontrolled environments, it is greatly affected by vibrations. This paper presents a structured-light sensor based on two laser stripes that provides a 3D reconstruction without vibrations. Using more than one laser stripe provi...
Mechanical vibrations of different products generate usually noise and additionally tactile information. In most cases, these auditory and tactile information are non-stationary signals. In the present study, a pilot psychophysical experiment was conducted to investigate the influence of non-stationary vibrations on the quality of non-stationary product sounds. In this experiment, non-stationar...
