- Description
- 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; offers are being requested and a written solicitation will not be issued. This notice is being issued as a Request for Quotations (RFQ) for Quantity of 1 Job: Assessment of the Dynamic Behavior of a High-Speed Foil Thrust Bearing Test Rig (Oil-Free Turbomachinery) Overview The High-Speed Thrust Bearing Test Rig at NASA Glenn Research Center is capable of testing oil-free thrust bearings up to 80,000rpm and 540?C (1000?F). This turbine-driven rig consists of a rotating shaft supported radially by foil journal bearings and axially by an active magnetic bearing, with a thrust runner bolted to the shaft. Foil thrust bearings are mounted on a nonrotating shaft and loaded axially against the rotating runner, while measuring reactionary torque of the test bearing. A more detailed description of this test rig may be found in the sources listed at the end of this document. As delivered, the test rig was equipped with a hydrostatically supported piston system to load the test bearing, allowing for high-temperature operation. However, axial vibratory modes at certain operating conditions restrict the usefulness of this arrangement, and subsequently an arrangement with mechanical loading and support has been substituted, with only room-temperature test capability. As part of a facility upgrade plan, NASA intends to award a contract to assess the dynamic behavior inherent to this test rig and recommend potential solutions. Contract Requirements The requested work entails both onsite and offsite activities to assess the axial dynamic behavior of the rig rotor system. First, the contractor shall travel to NASA GRC to collect dynamic data from the test rig during operation over the course of 2 consecutive business days. The contractor shall provide a standalone data acquisition system and any sensors and instrumentation required to measure vibrations, axial displacement, and any other qualities the contractor deems necessary. Additional instrumentation on the test rig may be used by the contractor to further provide data, and the Government may make available additional sensors and equipment at its discretion. The contractor shall record simultaneous measurements of the axial position of the rotating shaft and of the test bearing load piston. The frequency and phase response of the magnetic bearing controller shall be measured and reviewed to be incorporated into the system dynamic model. NASA will provide and install a test thrust bearing, and NASA-designated personnel will be responsible for safe operation of the rest rig during this data collection phase. Following the onsite collection of dynamic data, the contractor shall create a model for dynamic analysis to predict system behavior. This model will be compared to the collected test data in order to determine axial resonances and mode shapes. The control algorithm for the magnetic bearing shall be examined for appropriateness and alternate implementations investigated if warranted. Derating the magnetic bearing load capacity to achieve better dynamic response at low loads will be considered. The contractor shall submit a final report documenting their detailed findings and conclusions. Magnetic bearing controller bode plots are to be provided along with details of the control algorithm, as well as approximate transfer functions for both control and plant. Details of the magnetic bearing including current and loads in appropriate units shall be provided in the report. Axial resonance modes shall be documented along with parameterized expressions governing the behavior. The contractor shall recommend one or more possible solutions to improve system dynamic behavior, including updated control hardware and changes to the control algorithm, if required. The contractor shall deliver this final report within one month of completing the onsite work.
