SignalStar Mixed Mode
Mixed mode testing is used to simulate the vibration
environment of structures where there is a combination of
broadband and cyclic or narrowband energy. Cyclic energy can
be in the form of sine tones (line frequencies) or narrowband
random. Examples of Sine on Random (SOR) vibration include
helicopter vibration, where random vibration due to turbulence
and sine vibration due to rotor blade frequencies are
combined. Vibration from tracked vehicles is typical of Random
on Random (ROR), where narrowband random is superimposed
on broadband random. For both sine on random and random
on random, the sine and narrowband component frequencies
can be fixed or swept. The system also allows for rapid on/off
control of narrowbands to simulate gunfire.
