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