This paper presents findings from an experimental investigation employing this novel approach to identify the frequency signatures of a building under ambient excitations. The results demonstrate that this method effectively analyzes the dynamic properties of the structure, offering a promising solution for structural health monitoring applications.

Pilots at the National Test Pilot School are conducting a Ground Vibration Test (GVT) on an Aermacchi MB-339, a military jet trainer and light attack aircraft, to analyze its dynamic behavior under varying conditions.

Crystal Instruments attended the Fourth Vibration Institute Middle East Training Conference 2024 (VIME24) from November 11-13 at Al-Khobar, KSA.

The flagship data acquisition system Spider-20HE was used to gather vibration data for modeling and vibration suppression of rotating machines.

Ground Micro-Vibrations, also known as Seismic Vibration or Floor Vibration, refers to a kind of vibration noise with a small amplitude caused by non-earthquakes on the earth's surface. These vibrations are usually generated by natural vibration sources (such as wind, waves, etc.) or artificial vibrations (such as machine vibration sources, vehicles, etc.), that are a stable non-repetitive random fluctuation on the ground. Seismic Vibration is characterized by being of low frequency and small amplitude, and its displacement is generally only a few microns to tens of microns, with a frequency variation range between 0.3-5.0 Hz.

Dr. James Zhuge will chair a Dedicated Session: Data Acquisition Integrated with Space Technology at the upcoming SAVE 2024 conference in Dallas, Texas on Wednesday, November 6, 2024.

The flagship data acquisition system Spider-20HE was used to gather vibration data on a rotor-bearing setup.  This vibration data was extrapolated and utilized for two neural network models.
