Half-sine shock pulse calculator
WebMar 20, 2024 · An example of a classical shock test definition might look like the following: “ 3 – 10mS, 20Gpk, half-sine pulses in all six orthogonal axes for a total of 18 shocks.” While vibration test standards often define classical shock pulses, more advanced shock testing may require a complex transient pulse that cannot be replicated by a ... WebClassical Shock control. A controller feature within a vibration test system to produce shock pulse signals, such as half-sine, haversine, sawtooth and triangular. Classical shock control creates a series of pulses to excite the device or structure under test, measures the structure’s response and performs a spectral analysis to determine its ...
