15 صفحه اولVibration - Basic Concept
Sounds are variations in pressure that propagate in an "elastic" environment, usually air, which can generally be perceived by human ears. A well-known example of variation in pressure is the one that takes place in the atmosphere, but these air changes are too slow to be heard. However, if these changes occurred at least 20 times per second, we would perceive them as sounds. In fact, man can h...
متن کاملVibration Isolation for Scanning Tunneling Microscopy
Scanning Tunneling Microscopy measures tunneling current from conducting surfaces. Through analysis, it is possible to make a three dimensional picture accurate on an atomic scale of a surface and probe microscopic phenomenon. The procedure is dependent on the distance between the surface of the microscope tip and the sample surface. High tolerances on a scale less than an angstrom are required...
متن کاملDecentralized control for multichannel active vibration isolation
This paper describes a theoretical and experimental investigation into an active four-mount vibration isolation system, in which electromagnetic actuators are installed in parallel with each of the four passive mounts placed between a three-dimensional piece of equipment and a vibrating base structure. Decentralized velocity feedback control is applied, where each actuator is operated independe...
