“SOURCE SELECTION INFORMATION – SEE FAR 2.101 and 3.104”

Electrodynamic shaker: The armature should be capable of a three-inch stroke, minimum. Shaker table should be a minimum of 17 inches in diameter and be capable of load support at a minimum of 1,900 pounds. The armature should have auto-centering capabilities when a mass is added. Displacement sensors, as well as, mechanical stops should be used to protect armature travel/stroke distance. Shaker table should be a minimum of 17 inches in diameter. The armature surface should include replaceable inserts for mounting using different bolts depending on the fixture or head expander being mounted. The shaker should include an isolation mount system to isolate the shaker from the floor so that energy is transferred to the test item and not translated to the facility. The shaker should include a gear drive system that will rotate the shaker into place to mount to a native slip table assembly.

Slip table: The system should include a slip table that will allow the shaker to be rotated and attached through the use of a magnesium drive bar (bull nose). The shaker will drive the slip table providing an expanded surface to mount fixtures and test items to during vibration or shock testing. The table working surface should have dimensions of 48 by 96 inches, with 3/8/-16 inserts on a 4 by 4-inch grid pattern. Closer to the forward end of the slip table (away from the shaker) a pattern matching the armature pattern should also be included on the top surface with the 3/8/-16 inserts. The base of the slip table top plate should be 1.5-inch magnesium and should ride on a natural granite bearing surface that includes orifices for oil distribution. The surface interface should be lubricated through use of a recirculating oil system with constant flow at each orifice regardless of load. The recirculating oil system shall include insulation and a heater to help maintain oil viscosity at lower temperatures seen during testing. The slip table should also include an isolation system to prevent vibration being translated to the facility.

Seismic base: The system should include a seismic base made from steel and concrete that will support the shaker and the slip table and isolate them from the facility floor.

DC field power supply: The system should include a DC field power supply rated to drive the field coil in the shaker.

Power amplifier: The system should include a direct coupled Class D high efficiency power amplifier with a 240 kVA output. The amplifier should include insulated gate bipolar transistors (IGBT).

The amplifier should include a user interface that incorporates remote operation, startup, standby, input type selection, and gain control.

The amplifier should also display voltage and current monitoring, and status.

Recirculating water cooling system: A closed loop recirculating water cooling system should be included. The water cooling system is used to cool both internal shaker components, as well as, the power amplifiers. The recirculating water cooling system includes a heat exchanger that interfaces the distilled water pumped through the system components with glycol that is run from an external chiller. The recirculating water cooling system includes filtering and pressure monitoring, and appropriate connections and hoses for interfacing with the external chiller and piping to the shaker and power amplifiers.

External cooling blower: The system should include an external cooling blower that is capable of appropriately cooling the magnetic coils and internal cavity of the shaker. The blower should come with flexible air ductwork allowing it to connect to the shaker from outside of the building, and be capable of interfacing with the vertical stack.

Cable and hoses: Electrical cables and air and water hoses needed to connect and cool the power amplifiers and electrodynamic shaker should be provided with the system.

The electrical cables will need to be 100 feet in length to connect the shaker and the amplifier.

Head expander: The system should include a 48 by 48 inch, Magnesium head expander. The head expander will increase the mountable surface area of the test table by attaching to the armature through a matching mounting hole pattern. The head expander will include a thermal insulating barrier for testing at temperature. It should include additional support sin the form of bearings and air bags to reduce the load on, and work in concert with, the shaker. It should include a 4 by 4-inch grid of 3/8-16 threaded inserts for fixture mounting.

Delivery of the electrodynamic shaker vibration test system is 19 months after issuance of the contract. Two-day system checkout from factory engineer is to follow installation.

The Government’s minimum needs have been verified by the certifying technical and requirements personnel.

4. Statutory Authority Permitting Other Than Full and Open

Competition

10 U.S.C. 2304(c)(1) as implemented by Federal Acquisition

Regulation (FAR) 6.302-1: The property or services needed by the agency are available from only one responsible source or only from a limited number of responsible sources and no other type of property or services will satisfy the needs of the agency.

5. Rationale Justifying Use of Cited Statutory Authority

In order to establish commonality between Naval Sea System

Command (NAVSEA) Warfare Center’s Environmental Qualification Test (EQT) laboratories, common capital EQT equipment must be established for use in the laboratories.

Common equipment allows for standardized procedures, 1 IAW NMCARS 5206.304(a) If the dollar value of the contract is negotiated at a level that exceeds the dollar threshold of the original justification approval authority, a new justification approval shall be obtained from the appropriate approval authority prior to award.

logistics, sparing, maintenance, workload sharing, and personnel sharing. Common equipment will readily facilitate common EQT control strategies, test plans, data capture techniques, analysis algorithms, and test reporting.

Procuring common equipment across the laboratories increases operational efficiencies relative to EQT and provides a platform for high velocity learning. Implementing standardized equipment will ensure the Warfare Center’s EQT facilities are within the required criteria.

Naval Sea System Command Warfare Center Subject Matter

Experts (SME) have determined the equipment that is most appropriate to meet these requirements. Unholtz-Dickie vibration test systems, the vibration control system described in this document, has been determined to meet the requirements.

The Naval Sea System Command (NAVSEA) Warfare Centers

Industrial Services and Environmental Qualification Testing Collaboration team, led by the Test and Evaluation (T&E) Directors of Naval Surface Warfare Center, Dahlgren Division and Naval Undersea Warfare Center Division, Newport, have documented this determination in Joint Letter NSWCDD 3965 Ser E40/009 & NUWCDIVNPT 3965 Ser 70/055. The NSWC IHEODTD T&E Director has met the same determination and endorsed this policy for NSWC IHEODTD.

The current status of vibration test systems in NSWC

IHEODTD, Research Development Test and Evaluation (RDT&E) Department, includes three Unholtz-Dickie systems. The vibration test system described in this document will replace one of the three current systems. Operational efficiency is maintained by the interoperability of the systems. Vibration controllers can be interchanged between systems when necessary, in order to mitigate maintenance, and other operational issues, and eliminate down time.

Vibration profiles can be transferred between systems because the same software is utilized for all the systems.

Measured data can be transferred between systems, as well, allowing for data aggregation and analysis. System congruity also allows for a single set of hardware (signal conditioners, etc.) to be maintained for all systems.

Unholtz-Dickie, the Original equipment manufacturer (OEM) of the vibration test system, is the sole vendor of newly manufactured Unholtz-Dickie vibration test systems. The vibration test system has configurable features and is built to order.

Based on the above, Unholtz-Dickie is the only responsible source that will satisfy agency requirements.
