Abstract

During periodic checking of vibration transducers with a shaker table, using sinusoidal excitation, it was noticed that the waveforms produced by the transducers at low frequencies showed significant distortion. It appears that this is due to unintended forces on the transducer due to the signal cable. One of the ramifications is that the measured low frequency spectrum will potentially contain artifacts that are not directly due to the vibration input. Empirical results are presented of a mini-study of the effects on transducer signal output of different types of signal cable and cable dressing.
