RTCA DO-160G Vibration and Shock Testing

DES recently completed RTCA DO-160G vibration and shock testing for DB Integrations in Allentown PA, a manufacturer of aircraft components.  The testing was performed on ARINC 600 Mounting Trays.  The trays were vibration tested for use on fixed wing aircraft (Section 8, Category S) and for use on helicopters (Section 8, Category U2).  Shock testing was also performed per Section 7, Category A in RTCA DO-160G.  The trays withstood the rigorous testing that took 3 days to complete.

DES has extensive experience performing testing to standards such as RTCA DO-160G.  For more information contact DES or call 610.253.6637.

MIL-STD 810, Method 516, Shock Testing Overview

Shock testing according to Procedure I of MIL-STD 810, Method 516 is intended to test products while they are operating to see if any functional problems occur and to determine if they survive without damage.  The applied shocks usually represent those that may be encountered during operational service.  This article will focus on the shock test condition when measured field data is not available and the testing will use classical shock impulses.  The terminal peak sawtooth is the default classical shock pulse to be used for this condition.  Figure 516.7-10 from MIL-STD-810 shows its shape and tolerance limits.  Table 516.7-IV contains the terminal peak sawtooth default test parameters for Procedure I -Functional Test.  In limited cases a half sine shock impulse is specified.  Its shape and tolerance limits are shown in Figure 516.7-12.
