Method & Evidence

AimTo investigate the correlation between vibration signatures and the progression of rolling contact fatigue damage in test specimens.
MethodExperimental and Simulation-based research
ProcedureThe study involved setting up a rolling contact fatigue test bench, performing static and modal finite element analyses (FEM) on the bench structure, conducting rolling and sliding tests on specimens, and implementing a system to monitor vibrations using piezoaccelerometers. A virtual instrument was developed for data acquisition and analysis. The surface profile of the specimens was periodically measured to quantify damage, and vibration data was analyzed using spectral analysis (FFT, PSD, waterfall) and custom digital filters for real-time damage estimation.
