Structural Dynamic Modeling Tool for Virtual Vibration Testing Of External Stores

ACTA proposes a SBIR Phase I project to develop an accurate structural dynamic modeling tool for virtual vibration testing of external stores. The goal is to develop a structural dynamics modeling tool which will provide an accurate physics-based solution for predicting non-linear vibration response, and employ the modeling tool for conducting “virtual” vibration testing. This requires a thorough understanding of the relevant physics, the critical technical issues involved, and the resources available to model the physics and address these issues. The proposed technical approach will (1) enable analysis of laboratory test configuration(s) for comparison with “real world” store/aircraft systems and their dynamic environments, (2) facilitate the “tuning” of laboratory test configurations to more accurately represent the physics and service environments of “real world” store/aircraft systems, and (3) enable the “virtual vibration testing” of external stores that have received minor modifications relative to stores that previously have undergone successful vibration testing in the laboratory.
