Rapid, Accurate, Satellite Structural Dynamic Modeling Methods for Responsive Space Needs

This proposal addresses the development of a software tool that can quickly and accurately predict the structural dynamic response of satellites to meet the needs of Responsive Space. This tool will be particularly applicable for structures which are assemblies of off-the-shelf or standardized components, but which cannot be test-verified because of cost, schedule, or physical limitations of the structure. This Phase I SBIR program will demonstrate that system verification can be done using probabilistic methods to propagate uncertainties associated with major components and with the joints that attach them. A detailed design specification document will be created to ensure that all of the requirements of the solicitation are met. An easy-to-use, GUI-driven tool will be created that incorporates the design specifications. Risks associated with the development of the full-scale prototype tool will be identified and risk reduction plans defined for Phase II. BENEFIT: The system dynamic response tool that will be developed under this SBIR will provide a means for satellite systems to be flight qualified without test verification. The tool will be efficient, robust, and easy-to-use so that an analyst will be able to meet the schedule requirements of Responsive Space. Once the path for verifying space hardware without test has been established, the tool will be in demand for traditional satellites or other space payloads on programs that cannot otherwise test-verify the fully assembled system due to a lack of facilities, schedule, or funding. The methods developed here will also have broader application to the rapid evaluation of proposed new product configurations during product development in a wide number of industries including automotive, power generation, commercial aircraft, and industrial machinery.
