What is RMS value in vibration testing?
In vibration testing It is generally demanded that a random Signal
should contain peak-values of three times the RMS value. The force
produced by an exciter is mainly limited by the heating effect of
the current. i.e. the RMS value. whereas the power amplifier rating
is influenced by the peak values.

Electrodynamic Shaker Vibrator Meet Ista Standard for Random
Vibration Resistance Test
sine and random electromagnetic high frequency vibration tester completely according to the standard design battery related
testing, simulation, under the certain condition of the vibration
test of battery, the battery or battery pack is fixed on the
vibration table, according to the prescribed frequency,
acceleration and displacement mode along the battery sample
vibration of three mutually perpendicular direction measured
battery should not leak, don't lose heart, not broken, no fire and
explosion.
