Phase II Amount
$1,485,779
Prediction of vibroacoustic and shock environments for Department of Defense and commercial launch vehicles, as well as for spececraft and satellites, is currently a costly and labor-intensive process. However, accurate environmental predictions are essential to ensure the reliability of vehicle structures and airborne equipment. The objective of this proposed program is to develop VISPERS, an expert system that will allow users to increase vibroacoustic prediction accuracy, reduce prediction costs, and improve productivity. To be successful, the expert system requires major scientific advances. Analysis tools and software need to be integrated into an efficient, easy-to-use interface; new database technologies need to be developed to allow rapid exchange of vibroacoustic data between distributed database servers; and the expertise that has been developed over the years needs to be quantified and packaged within an expert system framework. These tasks will be completed within the proposed Phase II project.
Benefits: The results of the proposed effort will help to reduce the cost and development time for new aerospace vehicles and improve the reliability of these systems for DOD, NASA, and commercial launch vehicles and spacecraft. Applications to automobiles, aircraft, and ship machinery are also possible
