Low-frequency resonance is a bigger problem than high-frequency resonance in general industrial machines. This little-recognized distinction is crucial in determining the best way to correct it.

An AC resonant test system is designed to generate high alternating voltage by forming a resonant circuit between the reactor and the test object. By operating at or near resonance, the system can ...

Sound is one of the great mysteries. It surrounds us all the time, yet it is invisible and has no smell. Except for the most booming of subwoofers, we rarely feel its vibrations on our skin. In fact, ...

Ferroelectrics found extensive uses in industrial applications because of their unparalleled electromechanical and electrical characteristics, for example, as actuators, sensors and capacitors [1], [2 ...

Piezoelectrical materials are utilized in various applications, from biomedical (cardiac, auditory, ultrasound, and numerous biosensors) to advanced electronics—including energy production and storage ...

According to string theory, absolutely everything in the universe—all of the particles that make up matter and forces—is comprised of tiny vibrating fundamental strings. Moreover, every one of these ...

Mechanical resonance is a pervasive problem in servosystems. Most resonance problems are caused by compliance of powertransmission components. Standard servocontrol laws are structured for rigidly ...
