Tool condition monitoring (TCM) plays a vital role in maintaining product quality and improving productivity in advanced manufacturing. However, complex machining environments often limit the ...

In linear scale, these peaks represent 2864 mm/s 2 /N for the open circuit and 1379 mm/s 2 /N for the active control with K 3. Thus, it is possible to see a drop of more than 50% in the vibration ...

The Institute of Physics of Materials of the Czech Academy of Sciences (IPM CAS), located in Brno, has acquired a CeraFab ...

Wide-band vibration is abundant in various industrial equipment, but extracting low frequency energy is challenging. Here, we demonstrated a trapezoidal cantilever-structure triboelectric ...

Low-severity stator inter-turn short circuit (ITSC) and orbital eccentricity in synchronous generators (SMs) might not result in clear features or fault characteristics using vibration signals.

VibrationShockMonitor Arduino - Continuously sample a piezo vibration sensor and a 6-axis MPU-6050 accelerometer. • Vibration event: piezo voltage > threshold → check accelerometer. • Shock event: ...
