AFWAL-TR-87-3069 (VOL. IV - SYSTEM MODELING TECHNIQUES), TECHNICAL REPORT: EXPERIMENTAL MODAL ANALYSIS AND DYNAMIC COMPONENT SYNTHESIS (DEC-1987)

AFWAL-TR-87-3069 (VOL. IV - SYSTEM MODELING TECHNIQUES), TECHNICAL REPORT: EXPERIMENTAL MODAL ANALYSIS AND DYNAMIC COMPONENT SYNTHESIS (DEC-1987)., System Modeling techniques have become more and more practical in the application of industrial design and troubleshooting of vibration problems in the last few years. Sophisticated commercial codes, such as SDRC\'s SMURF and SYSTAN, SMS\'s SDM, are very popularly used by the industrial engineers as one of the integral parts in the state of the art of Computer Aided Engineering. This report presents the reviews of the theoretical basis for the current methods of the System Modeling techniques along with a newly developed Component Mode Synthesis method. The effects of errors existing in the experimental modal model, validation methods of experimental model, and normalization of measured complex modes are also presented as part of the efforts to link the experimental model to the current system modeling techniques. Case studies of a H frame are presented and conclusions are made with respect to the effectiveness of different system modeling techniques.
