DATA ITEM DESCRIPTION
Title: VIBRATION SURVEY REPORT
Number: DI-NDTI-81587 Approval Date: 5 October 2000
AMSC Number: G7402: Limitation: N/A
DTIC Applicable: No GIDEP Applicable: No
Office of Primary Responsibility: G/Y243
Applicable Forms: N/A
Use/relationship:
This report covers the results of specified vibration survey tests
performed on equipment to determine if any resonant condition exists
within the equipment, and also the magnitude of resulting acceleration
forces as they relate to possible over stress of assemblies or
components. The report will be used by the procuring activity to
determine the readiness of the equipment for Environmental Stress
Screening (ESS) and reliability tests.
Requirements:
1. Reference documents. None
2. Format. Contractor format is authorized
3. Content. The report shall contain the test data obtained during
specified vibration survey tests and shall include:
a. Description of the vibration survey test, including the following:
(1) Location and axis of accelerometers
(2) Levels and axis of imposed vibration.
(3) Techniques used to perform the survey and record accelerometer
out put.
(4) Vibration check of fixtures to assure there are no fixture
resonances in the vibration test frequency range.
(5) Vibration sweep rate and dwell time at resonances.
(6) Rationale for selection of items monitored by sensors.
b. Vibration measurements taken, under specified test conditions, of
the vibration response of the structural package itself, and of integral
parts/subassemblies internally mounted.
c. A comparison of the vibration data taken during vibration tests
with the vibration data determined analytically or the vibration limits
recommended by the manufacturer of the part or by the contractor.
d. Description and identification of equipment under test, date of
test, and location of the test facility.
e. Methods and test equipment/instrumentation used to perform the
survey including manufacturer, model number, serial number, and
accuracies.
f. Discussion of vibration measurement accuracy.
g. Identification of any resonant condition exhibited during the
vibration test.
