Swept sine tests: SHM with logarithmic sweep of frequency range from min-to-max, 4 times (4 mins each time) for each of X, Y, Z axes.
Peak acceleration (G), Peak displacement, crossover freq, freq range -for each use condition.
Example: Service condition 1, 20-2KHz, 4 mins/cycle, 4 cyc/axis, 3 axis.
Random vibration:Vibration applied for 30 minutes in each of the 3 orthogonal axes, X, Y, Z
RMS acceleration (G), RMS displacement, RMS velocity, - for each use condition
For each use condition, the selected test parameters above result in PSD values for different frequencies, generating plots/profiles showing PSD (intensity of acceleration power, measured in G^2/Hz) variation across a range of frequencies (2-500Hz).
Area under PSD-frequency plot is RMS acceleration (G)
Mechanical Shock JESD22-B110B:
Component or sub-assembly free-state: 5 shocks x 3 axes (X, Y, Z) x 2 directions/axis, minimum (total) 30 shocks
Sub-assembly mounted: 2 shocks x 3 axes (X, Y, Z) x 2 directions/axis, minimum (total) 12 shocks
Peak acceleration (G), pulse duration, velocity change, equivalent drop height.
Example: Service cond. B, 1500G, 0.5 ms, 5 times/axis, 6 axis
