Abstract
ACTA and Sandia National Laboratories propose to quantify and propagate substructure modeling uncertainty for reduced-order substructure models to higher levels of system assembly, thereby enabling predictive simulations of engineering designs with quantified margins and uncertainties for model-based flight qualification of complete spacecraft. A critical part of this process is the accurate modeling of interface structures, especially nonlinear interface structures that connect major substructures, and the quantification of their uncertainties. By developing generic uncertainty models for reduced order models of specific substructures, NASA will be able to quantify margins and uncertainties for structural systems outside the domain of model validation tests.
