Sensitivity Analysis for Design Optimization Integrated Software Tools

The objective of this Phase 2 proposal is to provide a new set of sensitivity analysis theory and codes,the Sensitivity Analysis for Design Optimization (SADO) software that integrates with the existing NASA O3 Tool. In this Phase II effort, the sensitivity codes developed in Phase I will add functionality to simplify Ground Vibration Test, or model tuning, by calculating a number of error metric that can be used as objective functions in the tuning process. The approach will be implemented for two basic types of responses, namely basic direct responses from the analysis (weight, frequencies, stresses) and special indices (MAC, Correlation Index, CG, Inertias) whose calculation was implemented during Phase I. Additionally, we will implement a domain specific language and interface specifications to simply the programming of optimization problems and incorporating additional analysis software tools for multiobjective applications. We will all implement software tools to use sensitivity analysis as system evaluation tool and for the development of reduced order models. We will use this software for two NASA relevant design projects, the ATW2 wing and the Hybrid Wing Body air vehicle.
