E-MAIL: Vicki E. Wampler, vicki.wampler@msfc.nasa.gov. This notice is a combined synopsis/solicitation for commercial items prepared in accordance with the format in FAR Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; quotes are being requested and a written solicitation will not be issued. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). Quantity: 1, Unit: Each, Description: Unholtz-Dickie Electrodynamic Exciter, Model T-4000 or equal that meets the following specifications: 1. The unit shall be capable of producing 45,000 lbf with a user defined random input spectrum and a table load of 1250 lbm utilizing an existing power source capable of producing 1500 Arms at 300 V. 2. The shaker shall have a continuous duty capability of 2" pk-pk. 3. The unit shall have a free-table acceleration capability of 150 g, and velocity capability of 165 ips. 4. All interlocks shall be 115 Vac. 5. The unit shall have an air-cooled armature. It shall be capable of cooling flow in either direction, thus allowing positive-pressure cooling with user supplied air or negative-pressure cooling with a user supplied exhaust fan. There shall be no fluid connections to the armature. 6. The armature's top surface shall be capable of sustained exposure to temperatures of -430 F for up to 8 hours while being supplied a constant positive-pressure, heated air-flow, air or GN2, through the body of the shaker to prevent frost or ice buildup. 7. The armature shall be of metallic, bolted or welded construction. The "spider" shall be a single piece, not bolted together. The spider shall be bolted or welded to the drive coil. Adhesive potting of structural or drive-coil members is not permitted due to the harsh service that the unit is designated for. The unit shall be routinely exposed to transient pulses in excess of 150 gpk with velocities in excess of 150 ips. The armature shall be exposed to random inputs of 115 grms measured at the armature top surface for up to 8 minutes duration. 8. The armature top shall have a bolt pattern for fixture attachment (5' x 5' square, magnesium alloy head-expander, weight not to exceed 1500 lbs., 22" x 22" x 22" magnesium cube, weight not to exceed 230 lbs., 48" round, magnesium head-expander, weight not to exceed 590 lbs., and 22" x 22" magnesium alloy L-bracket, weight not to exceed 150 lbs.) that has 45, SS, .5-13 threaded inserts. These holes shall be arranged on bolt circles as follows: 0" dia with 1 hole, 4" dia with 4 holes, 8", 12", 16", 20", 24" all with 8 holes equally spaced. This is a requirement due to the large number of existing adaptive fixturing that this laboratory routinely uses. If the supplied unit deviates from this specification, it shall be supplied with a full complement of user-defined adaptive equipment that shall include head-expanders, cubes, and L-brackets such that the laboratories capability will not be reduced. 9. The unit shall be compatible with existing field supply and cooling packages (Unholtz-Dickie T-4000) in the facility. This unit is being purchased as a "drop-in" unit. The user will not make any facility modifications that are required to accommodate the supplied unit. The user will perform routine installation of the unit such as moving it into place, rerouting and connecting the drive cables, cooling duct, interlock lines, and field cooling-fluid hoses to accommodate the unit. 10. The unit shall be supplied with an integral base that supports the unit in the vertical configuration with air-bag vibration isolation. The air-bag isolation shall have provisions for being bypassed so that the exciter can be hard-mounted to the base structure for shock testing. The base arrangement shall allow for the unit to be rotated 90 degrees from vertical in at least one direction. 11. The unit shall arrive at MSFC assembled and ready for installation. 12. The armature of the unit shall not have a free-table resonance below 2000 Hz and shall not weigh more than 260 Lbs. 13. The armature impedance shall be such that theunit can be direct coupled to the existing power amplifier (Unholtz-Dickie TA-660) without the use of a matching transformer. 14. Unit shall have a table suspension stiffness of 3000 lbs/in nominal. 15. The unit shall include 50' of armature and field cabling and hoses along with 10' of 10" duct for the air-cooling. 16. Unit shall have integral interlock protection switches for cooling-air flow, overtravel, and field temperature. 17. The unit shall be able to center a 3,500 lb load either automatically or manually and shall have a visual indicator mounted on the unit to indicate centered position. 18. The unit shall be provided with two complete sets of operation and service manuals. 19. The contrator shall provide one day of onsite installation and startup support for the unit once it has been moved into place in the facility and connected to the laboratories system. The provisions and clauses in the RFQ are those in effect through FAC 97-10. This procurement is a total small business set-aside.
