1.0 TEST ITEM One (1) Limitorque SMB-000/HOBC Actuator with a Seismic Bracket was submitted bv Limitorque Corporation for seismic vibration testing at Acton Environmental Testing Corporation (AETC).

Note:

Actuator was'lso subjected to additional seismic excitation as documented in Acton Report'f14331-2.

The purpose of this test was to subject the actuator speci-fied in section 1.0 above to the seismic vibration test specified in section 3.0 below to determine its ability to withstand such vibration without evidence of mechanical damage, deterioration, loss of its ability to operate properly, or contact chatter in excess. of one (1) millisecond.

3.0 TEST PROCEDURES This test was performed under the direction of Mr. Paul Young of Limitorque Corporation.

The actuator was bolted to a test fixture supplied by Limitorque.

The test fixture was then securely attached to the single-axis table of the AETC seismic test facility.

3.2 Test Conditions All tests were performed at room temperature and pressure.

During the resonance survey specified in section 3.4 below, the actuator was not operated.

Du~ing the sinusoidal dwell test specified in section 3.5 below, the actuator was cycled open and closed at least once per dwell.

460 VAC 3g power was supplied to the actuator.

3.3 Test Monitorina The actuator was visually monitored for any evidence of 14331-3 Report No.

mechanical damage, deterioration or loss of its ability to operate properly.

The actuator was monitored with triaxial groups of accel-erometers by AETC personnel to determine its mechanical response during the resonance survey and sinusoidal dwell test specified in sections 3.4 and 3.5 below.

Data from these accelerometers through appropriate signal condition-ing was recorded on visicorder recording paper included with this report.

The eighteen (18) monitoring accelero-meters and one (1) control accelerometer were mounted as

~R The resonance survey consisted of a sinusoidal input with peak horizontal or vertical accelerations of 0.5g.

The resonance survey was conducted at a

sweep rate of 6 seconds/

Hz (1 octave/minute for Tests 58, 6B 5 BB).

The resonance surveys were performed as follows:

The sinusoidal dwell test was to be performed at the resonant frequencies found during the resonance survey (only those below 33 Hz) specified in section 3.4 above.

If no resonances were detected, then testing was to be performed at 33 Hz.

Each input at each test level was for a duration of thirty (30} seconds.

The input was applied as follows:

3.6 Sine C clin Test The sine cycling test consisted of a sinusoidal input cycling from 10 to 100 Hz and back to 10 Hz, at a sweep rate of two (2) octaves/minute.

The sine cycling test was performed for a period of ninety (90) minutes/axis.

The vertical or horizontal input was 0.025" DA from 10-24 Hz and 0.75g peak from 24-100 Hz.

The input was ap-plied as fo11ows:

The torque switch chattered at each test level.

Torque switch was defective be-fore testing.

Between TEST 6B and 7B, the housing of the limit gear switch was found to be loose and was retightened.

TEST 7B - The actuator was operated at each level and the torque switch chattered at each test level.

At the 6g level, a shift in response was detected at the motor end housing and actuator housing.

The mounting bolts between the motor and actuator were found to be loose and it seemed as if local yielding had occured.

The bolts were removed.

The holes in the actuator were recapped and new bolts, were installed.

TEST 9B - The actuator was operated at each level.

The torque switch chattered at 4g's, 59's and 6g's.

Mhen trying to re-move the unit from the test fixture, the bolt threads holding the test item to the fixture were found to have yielded.

The bolts were removed and replaced with new ones.

The torque switch chattered at 7g's, gg's, gg's, 10g's, llg's and 12g's.

TEST 118 - The actuator was operated at each test level.

The torque switch chattered at 7g's, gg's, gg's..10g's, llg's and 12g's.

Following ccmpletion of the 12g run, the coupling adaptor was found to be fractured in the same manner that previous couplings had fractured.

The coupling adaptor was replaced.

TEST 128 - The actuator was operated at each test level.

Xfter fsrst'attelapt at gg's, one of the finger basis of the gear limit switch fractured shorting input power.

The finger base was replaced and the test continued.

This necessitated moving accelerometers 17, 18 and 19 from the previous loca-tion to the thin metallic gear limit frame cover.

The actuator was operated manually by the representative from Limitorque after testing in each axis was completed.
