Jump Phenomena in Frequency Response Spectra Due to the Use of Mechanical Exciter.
ABSTRAK Jump phenomena commonly occurred on vibration tests of structures with soft or hard spring systems. These phenomena normally caused lost of data at about resonant frequencies. The steady state vibration test, using a mechanical exciter as well as a magnetic exciter, on a simple reinforced co...
