1.0 INTRODUCTION

1.1 Purpose

The purpose of this report is to document the results of MIL-STD-167-1 Vibration

Type I testing conducted on the Argon Ship Exploration Equipment Increment E(SSEE-E) System for 901D. Testing was conducted June 10 through 26, 2003.

1.2 Background

The Ship Exploration Equipment Increment E (SSEE-E) System is composed of

four 901D Model 100, externally-isolated cabinets, with the components beinglocated per the COTS equipment layout shown in Section 1.1 of 901Ds Shock

and Vibration Test Procedure for Argon Engineering Ship Signal Equipment

Increment E (SSEE-E) Data Item S00H, Rev. A, dated 24-April-2003. TheSSEE-E is planned for installation on all U.S. Navy ships. The first systems in

service will be installed onboard AEGIS cruisers and LHA5 ships, followed bythe LHD8 and LPA ships. It is a first article item (new production) and requires

vibration qualification in accordance with MIL-S-167-1 (Type 1).

1.3 Scope

This report describes the activities performed during the pre-test period, the

fixture and equipment installation on the vibration test machine, actual test

operations, instrumentation setup, physical inspections, operational tests, and testresults.

4) CCOP Rack

The equipment under test (EUTs) were interconnected such that operability checks

could be performed. Initially, the CCOP was installed on the vibration table (see

Photograph Nos. 1 and 2) while the System Control, V/UHF Receive, and HFReceive Racks were test support items. The CCOP Rack test effort is described in

Section 6.0.

After completing CCOP Rack vibration testing, the CCOP Rack was removed from

the table and replaced with System Control Rack (see Photograph Nos. 5 and 6).The vibration test effort associated with System Control Rack is described in Section

7.0. In this arrangement, the CCOP, V/UHF Receive, and HF Receive Racks weretest support items.

After completing System Control Rack vibration testing, the System Control Rackwas removed from the table and replaced with V/UHF Receive Rack (see

Photograph Nos. 11 and 12). The vibration test effort associated with V/UHF

Receive Rack is described in Section 8.0. In this arrangement, the CCOP, SystemControl, and HF Receive Racks were test support items.

After completing V/UHF Receive Rack vibration testing, the V/UHF Receive Rack

was removed from the table and replaced with HF Receive Rack (see Photograph

Nos. 16 and 17). The vibration test effort associated with HF Receive Rack isdescribed in Section 9.0. In this arrangement, the CCOP, System Control, and

V/UHF Racks were test support items.

4.0 VIBRATION TEST MACHINE

Manufacturer: L.A.B. CorporationModel No: RVH-72-5000

Serial No: 466013

5.0 TEST PROCEDURE

All EUT was vibration tested in three orthogonal axes (vertical, side-to-side and

front-to-back directions), from 4 to 33 hertz. A vibration test sequence wasperformed for each axis. As specified in MIL-S-167, the sequence included an

exploratory vibration test, variable frequency test and endurance test. The test

sequence in one direction was successfully completed before proceeding to test inanother direction.

5.1 Mode of Operation

The EUT was energized with 110 VAC power and operating during each

vibration test sequence.

5.2 Exploratory Vibration Test

The test item was secured to the vibration table and vibrated at frequencies

ranging from 4 to 33 hertz at table vibratory amplitudes of 0.020 0.004 inch(peak-to-peak). Each integral frequency was maintained for a minimum of 15seconds and frequencies and locations of resonances were noted.


13/50

R030701 6

5.3 Variable Frequency Test

The test items were vibrated at frequencies ranging from 4 to 33 hertz in discrete

frequency intervals of 1 hertz at the amplitude shown in Table 1. Each integral

frequency was maintained for a minimum of 5 minutes and results for the EUT

are recorded in Section 6.0 through 9.0 of this test report.

Table 1. Table Amplitudes

Frequency (Hz.) Amplitude (inch peak-to-peak)

4 to 15 0.060 + 0.012

16 to 25 0.040 + 0.008

26 to 33 0.020 + 0.004

5.4 Endurance Test

This test was performed for 2 hours at either mount resonant frequency, structuralresonant frequency or 33 hertz if no structural or mount resonant frequency was

identified by the test engineer. If more than one resonance was identified the test

was performed at 1 hour for each identified frequency. The table amplitudes were

as noted in Table 1.

6.0 VIBRATION TEST OF CCOP RACK

6.1 Test Installation of CCOP Rack

The CCOP rack was installed on the test fixture. The rack was mounted to the test

fixture using three mount interface plates that attached the eight ShockTech 901D

isolators to the cabinets.

The 6 base isolators were bolted to the interface plates (3 mounts per plate) with a

total of 27 (9 per isolator) -20 UNC Grade 5 bolts, flat washers, lock washers,

and with nyloc nuts. The 2 sway brace isolators were bolted to the interface platewith a total of 12 (6 per isolator) -20 UNC Grade 5 bolts, flat washers, lock

washers, and with nyloc nuts.

All three-interface plates were attached to the test fixture using sixteen -13

Grade 5 bolts. The test fixture was clamped to the vibration table. Photograph

Nos. 1 and 2 show the installation on the table.

6.2 Instrumentation

One accelerometer was located at the center of the vibration table to measure

table amplitudes and three accelerometers were located on the fixture or the EUT.

The locations of the gauges are listed in Table 2. Photograph Nos. 3 and 4 show

6.5.1 Front-to-Back Exploratory Test

Prior to the front-to-back test, the test fixture was unclamped from the vibration

table, rotated 90, and re-secured to the table. Photograph No. 3 shows the testsetup in the rotated configuration. The vibration table was excited in the front-

back direction at discrete frequencies ranging from 4 to 33 hertz. A mount

frequency was identified at 8.0 hertz and there were no structural resonancefrequencies identified.

6.5.2 Front-to-Back Variable Frequency Test

Single amplitude results from the front-to-back variable frequency test are

summarized in the table below. A mount frequency was equally identified at 8.0

and 9.0 hertz and there were no structural resonance frequencies identified.

7.0 VIBRATION TEST OF SYSTEM CONTROL RACK

7.1 Test Installation of System Control Rack

The System Control Rack was installed on the test fixture. The rack was mounted

to the test fixture using three mount interface plates that attached the eight

ShockTech 901D isolators to the cabinets. The 6 base isolators were bolted to theinterface plates (3 mounts per plate) with a total of 27 (9 per isolator) -20 UNC

Grade 5 bolts, flat washers, lock washers, and with nyloc nuts.

The two sway brace isolators were bolted to the interface plate with a total of 12(6 per isolator) -20 UNC Grade 5 bolts, flat washers, lock washers, and with

nyloc nuts.

All three-interface plates were attached to the test fixture using sixteen -13

Grade 5 bolts. The test fixture was clamped to the vibration table. Photograph

Nos. 5 and 6 show the installation on the table.

The endurance test (2 hours) was run at an excitation frequency of 7.0 hertz.



The vibration table was excited in the side-to-side direction at discrete frequenciesranging from 4 to 33 hertz. During the test, the control knob fell off of the

Receiver, R-2411, as seen in Photograph No. 10. The knob was re-attached and

the set screw tightened to prevent further loosening of the knob. A mountfrequency was equally identified at 8.0 and 9.0 hertz and there were no structural

resonance frequencies identified.

8.0 VIBRATION TEST OF V/UHF RECEIVE RACK

8.1 Test Installation of V/UHF Receive Rack

The V/UHF Receive rack was installed on the test. The rack was mounted to the

test fixture using three mount interface plates that attached the eight ShockTech901D isolators to the cabinets.

The 6 base isolators were bolted to the interface plates (3 mounts per plate) with a

total of 27 (9 per isolator) -20 UNC Grade 5 bolts, flat washers, lock washers,

and with nyloc nuts. The 2 sway brace isolators were bolted to the interface platewith a total of 12 (6 per isolator) -20 UNC Grade 5 bolts, flat washers, lock

washers, and with nyloc nuts. All 3 interface plates were attached to the test

fixture using sixteen -13 Grade 5 bolts. The test fixture was clamped to the

vibration table. Photograph Nos. 11 and 12 show the installation on the table.

table, rotated 90, and re-secured to the table. Photograph No. 17 shows the testsetup in the rotated configuration. The vibration table was excited in the front-back direction at discrete frequencies ranging from 4 to 33 hertz. A mount

frequency was identified at 8.0 hertz and there were no structural resonance

frequencies identified.
