Shock and Vibration
The ruggedized (-D version) of the modules are designed to withstand elevated levels of shock and vibration to be able to operate in
harsh environments. The ruggedized modules have been successfully tested to the following conditions:
Non operating random vibration:
Random vibration tests conducted at 25C, 10 to 2000Hz, for 30 minutes each level, starting from 30Grms (Z axis) and up to 50Grms (Z
axis). The units were then subjected to two more tests of 50Grms at 30 minutes each for a total of 90 minutes.
Operating shock to 40G per Mil Std. 810F, Method 516.4 Procedure I:
The modules were tested in opposing directions along each of three orthogonal axes, with waveform and amplitude of the shock
impulse characteristics as follows:
All shocks were half sine pulses, 11 milliseconds (ms) in duration in all 3 axes.
Units were tested to the Functional Shock Test of MIL-STD-810, Method 516.4, Procedure I - Figure 516.4-4. A shock magnitude of 40G
was utilized. The operational units were subjected to three shocks in each direction along three axes for a total of eighteen shocks.
Operating vibration per Mil Std 810F, Method 514.5 Procedure I:
The ruggedized (-D version) modules are designed and tested to vibration levels as outlined in MIL-STD-810F, Method 514.5, and
Procedure 1, using the Power Spectral Density (PSD) profiles as shown in Table 4 and Table 5 for all axes. Full compliance with
performance specifications was required during the performance test. No damage was allowed to the module and full compliance to
performance specifications was required when the endurance environment was removed. The module was tested per MIL-STD-810,
Method 514.5, Procedure I, for functional (performance) and endurance random vibration using the performance and endurance levels
shown in Table 4 and Table 5 for all axes. The performance test has been split, with one half accomplished before the endurance test
and one half after the endurance test (in each axis). The duration of the performance test was at least 16 minutes total per axis and at
least 120 minutes total per axis for the endurance test. The endurance test period was 2 hours minimum per axis.
