1. SCOPE

Vibration testing is performed at KSC to specifications or measured data in order to determine ac-ceptance/qualification criteria for GSE. GSE susceptible to vibration damage within a 1000 ft. radius of the launch pad must be tested for vibration endurance.

Avionics require random vibration testing up to 2500Hz and significant shock response spectrum test-ing. These tests require a mid-sized electro-dynamic shaker with a light armature and a guided slip ta-ble.

The contractor shall provide all personnel, labor, equipment, tools, materials, supplies, transportation, supervision and other items necessary to perform the requirements within this specification.

2. APPLICABLE DOCUMENTS

The following reference documents form a part of this document to the extent specified herein. The lat-est revision applies unless a specific revision is indicated.

3. REQUIREMENTS

3.1 Definition

The vibration table or shaker will be used for acceptance/qualification testing of GSE and flight hard-ware in the launch environment. Vibration table of different sizes and configurations are required to meet testing goals for varying test article sizes and vibration requirements. Due to new and evolving test requirements, we are seeking the maximum electro-dynamic system performance available on the commercial off the shelf market to meet the severe launch environments. The major parameters in con-sideration are maximum sine, random shock, shock level, maximum stroke, maximum velocity, maxi-mum slip table overturning moment, armature weight and associated resonance, and mean time between failures.

5. PACKING FOR SHIPMENT

Safe delivery in packaging is defined as delivery of a shipment to its destination with minimal damage to the package and no damage to the contents. The vendor shall provide outside package marking essen-tial to the identification of the item in detail, including appropriate identification of the product on both packages and shipping containers and all markings necessary for safe delivery and for storage.

6. NOTES

6.1 Intended Use

This document is intended to establish the requirements for fabrication and testing electro-dynamic shakers for use at the NASA Vibration Laboratory.

6.2 Definitions

For the purpose of this document, the following definitions shall apply.

a. Acceptance Tests - A test (or series of tests) conducted on each fabricated item to verify that it performs in accordance with expectations and requirements, that it is designed and produced with adequate workmanship and quality and that it is acceptable for delivery to the customer.

Acceptance testing often includes testing for certification and to detect latent manufacturing and workmanship problems.

b. Shall - Used to indicate a requirement which denotes a mandatory action.

c. Should – Used to indicate a requirement which denotes a good practice and is recommended, but not required.

d. Will – Used to denote an expected outcome.
