QMU in Integrated Spacecraft System Models

Completed Technology Project

Project Description

QMU in Integrated Spacecraft System Models
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 nonlinear components and interface structures, structures that connect major substructures, and the quantification of their uncertainties. By developing 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.
