Identifikation der Modellparameter Elastomechanischer Systeme Aus Schwingungsversuchen (Identification of the Model Parameters of Elastomechanical Systems from Vibration Tests)

摘要

The identification of model parameters from vibration tests on elastic structures was investigated. Starting from the mathematical model of the linear multiple vibrator with viscous damping, a time-domain method determines physical and modal system parameters. The emphasis was on the problems of the compensation of perturbation quantities and the applicability of incomplete models. However, the incomplete systems matrices have only a limited physical significance. The method was successfully tested on simulated and real test data of systems with five degrees of freedom.
