Integrated Structural Analysis and Test Program

An integrated structural-analysis and structure-testing computer program is being developed in order to:

• Automate repetitive processes in testing and analysis;
• Accelerate pre-test analysis;
• Accelerate reporting of tests;
• Facilitate planning of tests;
• Improve execution of tests;
• Create a vibration, acoustics, and shock test database; and
• Integrate analysis and test data.

The software package includes modules pertaining to sinusoidal and random vibration, shock and time replication, acoustics, base-driven modal survey, and mass properties and static/dynamic balance. The program is commanded by use of ActiveX controls. There is minimal need to generate command lines. Analysis or test files are selected by opening a Windows Explorer display. After selecting the desired input file, the program goes to a so-called analysis data process or test data process, depending on the type of input data. The status of the process is given by a Windows status bar, and when processing is complete, the data are reported in graphical, tubular, and matrix form.
