About this file
This statement of work outlines requirements for a resonance frequency and damping analysis system and supporting equipment. The National Aeronautics and Space Administration Shared Services Center seeks to procure an ICME RFDA system, including RFDA Professional hardware and software, data postprocessing tools, a room temperature reference sample, and an RFDA TE extension. The RFDA TE extension would provide furnace excitation and microphone assemblies, as well as RFDA TE software modified for automatic measurement cycles, continuous adjustable settings, and real-time display of results. Additional requirements include a computer system, manual and automatic excitation devices, vibration detection equipment, universal sample supports, and high temperature sample supports. All equipment shall be shipped to the Marshall Space Flight Center within 10 weeks of order.
The related federal contract opportunity is a special notice solicitation from NASA Shared Services Center for a resonance frequency and damping analyzer. The statement of work provides detailed requirements for the sought after equipment.
