This 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; quotations are being requested and a written solicitation will not be issued. The solicitation number is 53SBNB960140 and is being issued as a Request for Quotation (RFQ) using Simplified Acquisition Procedures. This action is unrestricted. The Standard Industrial Classification (SIC) Code is 3829. The small business size standard is 500 employees. The solicitation document and incorporated provisions and clauses are those in effect through Federal Acquisition Circular 97-12. The National Institute of Standards and Technology (NIST) has a requirement for one Fatigue-Rated Actuator and Control System to include a fatigue-rated hydraulic actuator, servovalve, displacement transducer, load cell, swivels, servo-controller, and service manifold. The design, physical, and performance characteristics of the components of the system shall include: (1) Fatigue-rated hydraulic actuator: (a) double rod cylinder (equal compression and tension capacity); (b) single piece rod and piston; (c) 21.0 MPa (3000 psi) operating pressure; (d) 445 kN (100,000 lb) to 534 kN (120,000 lb) dynamic force capacity; (e) 304.8 mm (12 in) or greater stroke; (f) ported for 757 l/min (200 gpm) or greater flow rate; (g) internal displacement transducer to measure piston/rod position, as described below; (h) load cell mounted on rod end to measure applied force, as described below; and (i) swivels on both the rod-end and base of actuator, as described below. (2) Servovalve: (a) 757 l/min (200 gpm) or greater flow rate; (b) manifold mounted directly on actuator; (c) capable of producing rated flow at all frequencies up to 10 Hz; (d) 90 degree signal phase at a frequency of 100 Hz or greater; and (e) matched for use with the servo-controller, described below. (3) Displacement Transducer: (a) for measuring the piston position; (b) linear displacement transducer; (c) internal to actuator: (d) hysteresis less than 0.1% of the transducer full scale; (e) non-linearity less than of 0.25% of the transducer full scale; and (f) matched for use with the servo-controller, described below. (4) Load Cell: (a) for measuring the applied force; (b) fatigue-rated transducer; (c) located on actuator rod end; (d) rated for actuator capacity or greater; (e) overload capacity of at least 150% of actuator capacity; (f) hysteresis less than 0.25% of the transducer full scale; (g) non-linearity less than of 0.25% of the transducer full scale; and (h) matched for use with the servo-controller, described below. (5) Swivels: (a) to allow mounting of actuator in a variety of structural test systems; (b) fatigue-rated; (c) rated for actuator capacity or greater; (d) include backlash adjustment; (e) allow swivel rotations of 30 degrees; and (f) allow tilt rotations of 7 degrees. (6) Servo-controller: (a) closed-loop, PID servo controller; (b) matched for use with the servovalve, load cell, and displacement transducer, described above; (c) capable of controlling the actuator in either force or displacement control; (d) provides signal conditioning for both the actuator displacement transducer and load cell; (e) capable of controlling the service manifold; (f) emergency stop; (g) failsafe interlocks available on stroke limits, force limits, error limits, external trigger(s), emergency stop; (h) can be operated remotely from a PC or workstation; and (i) accepts a 10 volt analog command signal. (7) Service manifold: (a) 757 l/min (200 gpm) or greater flow rate; (b) includes a filter that meets the manufacturer's specifications for the servovalve; (c) includes accumulators to minimize pressure fluctuations; (d) provides pilot valve pressure for the servovalve (if necessary); (e) provides full pressure and low pressure operating ranges; and (f) may be integrated into the servo manifold (optional). (8) General Specifications: (a) The actuator portsand service manifold shall all be designed for a peak flow rate equal to or greater than the servovalve. (b) The servovalve shall be capable of at least a 757 l/min (200 gpm) flow rate. (c) If the service manifold is not integrated into the servo manifold, the service manifold shall be connected to the actuator with flexible hose. (c) All hose connections (between actuator, service manifold, accumulators, and pump/reservoir) shall have either standard JIC 37-degree flare or SAE J518 C 4-bolt flange fittings. (d) All hydraulic components shall be designed for use with Mobil DTE 25 or Shell Tellus 46 hydraulic fluid meeting ISO 15/11 specifications. (e) Contractor shall provide all documentation on operation, adjustment, and maintenance of all components. Documentation shall include drawings detailing the external dimensions of the mechanical components. Required delivery is FOB Destination (Gaithersburg, MD) within 75 days after date of award. All shipping charges shall be included in the quote. Quoters shallprovide the information required by the provision at FAR 52.212-1 with their quotation.
