ABSTRACT: The test specimen was subjected to the i Seismic Test ref erenced in L imitorque Cor por ation Purchase Order Number 348572, dated 8/6/70.

The 5.36 por tian oF testing was complete with no discr epancies noted.

The 10 G par tion oF testing was termi-nated during the second cycle due to noted Fatigu'ng oF the gear limit sw it ch mounting hardwal-e .

Tost Report No. 2539A 4p;3 Issue 2 TEST PROCEOURE: The test specimen was secur ed to the ti v ibr a an rnachine, as shown in F igure and subjected to an exploratory scan f

over the r 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 v ibr ation.

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.

personnel The test specimen was energized dur ing testing and all electrical monitor ing was per Formed by Limitorque Cor parat: on

.

TEST RESULTS: The 5. 3 6 portion oF testing vras com-pleted wi th no evidence oF any dis-crepancies noted dur ing either axis oF test.

Our ing the exp lor atary scan oF the 10 G:.

por tion oF testing, the gear l'mit

'switch mounting hardwar e scr ews were tightened prior to loosened.'hese 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.  !
