The structural vibration of, for instance, microelectromechanical systems can be applied to perform some specific tasks in which micromanipulation is one of the examples. Since structural vibration has long been an important area of research, it is appropriate at this time to conduct an extensive review of its state of the art.

01.12.2016To overcome such limitations, a vibration-based fatigue technique is proposed, which entails the use of sandwich specimens whose geometries are optimized to reproduce the stress distribution observed during three point bend loading while vibrating at the first resonant frequency. The proposed vibration technique was experimentally validated.

Vibratory feeders are basically applied to a control function to meter or control the flow of material from a hopper, bin, or stockpile, much the same as an orifice or valve control flow in a hydraulic system. In a similar sense, feeders can be utilized as fixed rate, such as an orifice, or adjustable rate, as a valve.
