Virtual Vibration Testing Of External Stores Navy SBIR FY2010.1 Sol No.: Navy SBIR FY2010.1 Topic No.: N101-015 Topic Title: Virtual Vibration Testing Of External Stores Proposal No.: N101-015-1471 Firm: M4 Engineering, Inc. 4020 Long Beach Blvd Long Beach, California 90807 Contact: Kevin Roughen Phone: (562) 981-7797 Abstract: M4 Engineering proposes to develop a method for simulating store vibration response. This method will combine model reduction methods for the linear portion of the store models with nonlinear representations of joints and other nonlinear components. This development will result in simulation software that is capable of predicting nonlinear dynamic response using significantly fewer resources than conventional methods. The proposed technique will be an excellent compliment to modern test and analysis methods. Benefits: The proposed methods and software have the potential to dramatically improve the analysis and certification process for stores. Demand for this capability will be found in the government and at major airframe manufacturers. The proposed effort will satisfy this demand with a tool that is not only technically capable, but is easy to understand and use. The nonlinear dynamic simulation capability in the proposed effort will allow users to accurately and rapidly predict store vibration response in order to avoid unpleasant "surprises" during development, testing, and service. Initial implementation will focus on store analysis, however the capability created will apply to other structures subjected to nonlinear vibrations. Satisfying this existing demand will provide a tremendous commercial potential for this technology. Return
