In the case of simple static analysis or resonant-vibration problems, you can typically refer to “cookbook” equations in engineering text books to build sample FEA models.

A resonant condition exists if very small weights significantly change the amplitude and phase vector. If reducing the vibration in one direction (e.g., north-south) causes an increase in the other (e ...

Basically, linear resonant accelerators are a spring-mounted mass that move up and down, particularly at a specific frequency (hence the earlier pun). Oscillating the mass creates vibration in a ...

The developed energy harvester can tune its own resonance over a broad bandwidth of more than 30 Hz, and convert the absorbed vibration energy into electrical energy.
