Integrated Dynamic Test/Analysis Process Overview

An integrated approach to dynamic testing and mathematical model analysis is described. The overall approach addresses four key tasks, namely, (1) pretest planning and analysis, (2) test data acquisition, (3) data reduction and analysis, and (4) test/analysis correlation and mathematical model updates. Several key software programs are employed to accomplish this task. They are a leading finite element code, a sophisticated data analysis processor and a graphical pre- and post-processor along with an advanced interface utility. A spacecraft simulator structure is used to illustrate the integrated test analysis process.
