Structural and System Models 750135

This paper illustrates the use of the System Modeling Technique as it applies to structural vibration in the vehicle shake frequency range (5-25 Hz). The emphasis is on the applicability of the approach to a variety of structural subsystem analysis and synthesis techniques. Finite element and test modeling procedures are presented in an introductory manner with references provided to furnish the theoretical aspects. Comparisons of each modeling method are discussed from the vantage point of using the simplest approach to obtain the required results. Illustrations of complete system models are given with results compared to test.
