Dynamic range

Question

What is the dynamic range provided by VCS? What dynamic range is necessary for tests perfomance?

Answer

Dynamic range for sinusoidal vibration test perfomance is 80 dB, for random vibration – 60 dB.

Most of the tests are performed within the range of 1-100 g. Acceleration below 1 g almost does not affect the tested objects. Acceleration over 100 g can be produced only by powerful  electrodynamic shaker systems. Range of 1-100g makes only 40 dB. Hence, specified dynamic range is sufficient for tests perfomance.
