Parts analysis can be a complex and time consuming process for engineers without the use of a CAD package. By using models of parts, analysis of the dynamic properties of parts is automatic. Design engineers at McDonnell Douglas Aerospace (MDA) are sharing motion and stress analysis information with test engineers at the MDA Dynamics Laboratory.
Once rigid boundary conditions are established, torsional and linear forces are applied to test parts, and the resulting motion is analyzed automatically. I-DEAS software is being used to collect and analyze harmonics. In addition, the test software exaggerates part motion, helping engineers to visualize movement. Four views of the object under test are displayed electronically with resulting movement (front, side, top, and perspective). Bode plots can be created, and expected response can be compared with actual response. Both design and test engineers share analytical information across the MDA fiber optic network.
By comparing design and test analysis, engineers can ensure that stressed parts will behave as expected. Refinements in design are made quickly and easily to meet system requirements.
