Description

This is a combined synopsis/solicitation for commercial items prepared in accordance with the format in Subpart 12.6, as supplemented with additional information included in this notice. The contractor shall provide a hydraulic control system to be u sed to facilitate the testing of various vehicles for transportability requirements. Various size hydraulic cylinders combined with a computerized control system will be used to apply a constant load to the lifting or tie-down provisions on various vehicl es. The loading varies from 200 pounds-force up to 200,000 pounds-force.The overall package shall be ruggedly constructed intended to be used out doors under ambient environmental conditions. The package shall consist of a hydraulic power unit with a mot or starter/control, cabinet, an operator pendant, and linear actuators. All cabinets and interface devices shall be of a construction grade that will offer NEMA 4X protection. The operator interface shall be a pendent configuration that will be tethered to the main control cabinet and connected by an appropriate multi-pin connector offering the same grade of protection. All cables between the controller and valves\actuators shall be shielded. The operator interface shall be configured with a protective cover on the face for added protection. The sequence of operation shall be: The operator will turn the power unit on and cycle the power unit fluid through a bypass valve for a warm up phase if necessary. The optimum temperature is 125°. A temperatur e switch will generate an output to a lamp indicating the system is at operating temperature. The power unit will be controlled by the operator interface after initial start-up. The linear actuators required to provide the appropriate load will be selected and located in the test bay and all electrical and hydraulic conductors will be connected. The operator will move the actuators, independently if required, to a position that will allow the operator to connect the rigging. Once the rigging is connected to the actuators the operator will remove slack in the rigging for each actuator via the operator control pendant. When the load on each actuator is equalized a test button will be activated that will synchronize the motion of the two actuators. The actuat ors will hold this condition and be readied for the next phase. During the next phase, the control will be actuated and the actuators will retract at a described velocity slowly and in a synchronized motion. The actuator velocity will not exceed 3 inches per second during the retract or extend phase. The velocity in either direction is a variable control parameter. Once the actuators meet a pre-selected tension, they will immediately move into a force mode. Once in the force mode, control valves will ge nerate a variable pressure to the annular side to each actuator matching the tension output of each control device (load cell). The actuators will continue to retract until the pre-selected load is reached, hold the load for the length of time pre-selecte d then release to return to the initial setup position. If the system becomes out of balance more than a pre-describe tension over a pre-described time period the unit will alert the operator of an impending failure and immediately stop the test and relax the actuators. When the test has been completed or stopped do to exceeding preset limits, the actuators will move back to their initial setup position allowing the rigging to be removed or to setup another test. Diagnostic details will offer the operator insight as to the possible origin of a pending failure. The system components shall consist of: Power Unit. It is estimated that the power unit required to operate the system will contain the following items as a minimum, be trailer mounted with an appro priate cover for environmental protection, and equipped with a military style lunette hitch: L-Shaped 35 Gallon Reservoir and shelf base (suitable for forklift transport) to accommodate the motor and hose reels. Tank to contain a Tank Heater, 2000 Watt, 230 Volt, Adjustable Temperature setting for outdoor temperature conditioning during cold weather. Piston pump, maximum 6 gpm, 5000 psi, pressure ompensated prov ides hydraulic power for the system. This pressure permits the use of smaller actuators to achieve higher loads. 15 HP Electric Motor, TEFC, 460/230/60/3 1750 RPM 0-5000 psi gauge with snubber, rapid response relief valve, and a level/temperature switch. Air Cooled Heat Exchanger with electric motor fan drive appropriately sized to provide adequate cooling during extended periods of operation with outdoor ambient air temperature of 90 degrees. Pressure filter, 3-micron, micro-glass element, non-bypass, an d a return filter, 3-micron, micro-glass, with visual indicator.Four Lifting Eyes located to provide level and stable lifting of the power unit. Desiccant dryer/ breather. Electrical Panel mounted and wired to provide appropriate displays and terminal stri ps for unit operation, such as, Start/ Stop station, fused disconnect NEMA 12 enclosure, miscellaneous relay and terminal strips, setup for temperature control of the hydraulic oil. Storage for the operator interface with100 feet of cable. The cable has c onnectors on each end to permit routing the cable through small openings approximately 4 inches in diameter. 5000-psi electrical rewind dual-hose reels with 100' of 3/8-hose. Reels to be approved by the government. The Operator Interface shall provide a 15-inch touch screen interface that will allow the operator to establish the test parameters for up to 150 various test scenarios that shall include but not be limited to the following: Tension profile, Actuator Bore Size, Single or Dual Axis Test Switch over pressure, moving from a position based control to a tension based control. Initial Target Position Set Point, Target Tension Set Point, Duration to hold load, Control plots,Load cell read-out, up to four load cells, and Move actuator “A” or “B” selectable. The interface shall offer complete system status with respect to tracking position and tension forces in a dual or single axis control scheme and provide interfacing with National Instrument's LabView programming. Computers and peripherals shall be selected to withstand the rigors of a mobile environment. The Linear Feedback Actuators shall provide the means to apply loading to the test items. The actuators are sized to accommodate various test loading without overburdening the operator and consist of 3 sizes to meet the following specifications: Two each with 3.25-, 5-, and 8-inch bore diameters with a 24-inch stroke, Rod ends to be standard to industry with an MP-1 clevis mount, Actuators to contain mgnetostrictive feedback de vice for position control, All actuators will include an n appropriate servo valve-mounting surface located on the blind end with a steel tube connection made between the valve manifold and the head end. All ports will be SAE O-ring. All connectors will b e rated for NEMA 4X or IP70 service and Each actuator will be equipped with a 27B50F Direct Drive Servo valve supporting a flow of 5 gpm @ 1000 PSID.
