TEST PROCEOURE:
The test specimen was secur ed to the vibratian rnachine, as shown in Figure and subjected to an exploratory scan over the fr equency range oF 5 to 35 Hz in two (2) axes.
The explorstory scans were Followed by three (3) cycles oF vibration in each axis.
Each cycle consisted of twa (23 mihutes of vibra-t ion at a Frequency oF 35 Hz and an acceler ation level of 5.3G's followed b one
( 1 ) minute af no vibration.
The test specimen was then set up as shown in Figure 2 and subjected to the above mentioned test in the thir d axis.
At completion of this test, an addit-on explor atory scan was per Farm d over.tr.
Frequency r ange of 5 to 49 Hz and two
[23 cycle wer e perfor med at a fr e-quency.af 48 Hz and an acceleration level oF 10 G's.
The test specimen was energized dur ing testing and all electrical monitor ing was per Formed by Limitorque Cor parat: on personnel
TEST RESULTS:
The 5. 3 6 portion oF testing vras com-pleted with no evidence oF any dis-crepancies noted dur ing either axis oF test.
Our ing the exp loratary scan oF the 10 G:.
por tion oF testing, the gear l'mit
'switch mounting hardwar e loosened.'hese scr ews were tightened prior to the star t oF the First cycle.
0 The First cycle at 10 G's was then com-pleted wi h no discr epancies
- noted, After approx im'ately one
( 1 ) minute oF the second cycle, the test was termi-nated due to Fatiguing aF the gear lini switch mounting hardware.
Far additional infarmatian, r ef er to the Five {5) attached data sheets.
RECQMHENOATIONS None.
