Discover why your vibration data lies to you in mechanical engineering. We break down the deceptive traps that distort readings — improper accelerometer mounting and sensor placement, environmental noise and interference, aliasing from incorrect sampling rates, resonance confusion in FFT spectra, inconsistent measurement points, operating condition changes, and the subtle fault signatures that get buried in normal operational noise — plus exactly how to collect, interpret, and trend data you can actually trust for predictive maintenance and machinery reliability.
