Phase Tracking in
RSTD
The purpose of
Resonance Search, track and dell test is usually
for fatigue and durability test, it always can
find and test the weakest frequency point of test
unit, the dwell methods include locked frequency,
locked phase, peak amplitude tracking and phase
tracking. The latter two methods frequency will be
varied during the tracking and dwelling phase,
since as we know the resonant frequency is true
decreasing during dwelling period, while phase it
not, so these two methods maybe better in catching
with the resonance point. This paper will analyze
results between fixed frequency dwell and phase
tracking dwell, emphasizing on phase tracking and
introduce how to do this test with VENZO
controller VibExpert
software.
