Abstract
This paper deals with the identification of effective masses and modal masses from base-driven tests. When preforming a base-driven test with an elastomechanical structure, the structural responses can be related to the base accelerations and a modal identification of the structure can be accomplished. If, in addition, the base forces are measured, it is possible to determine the effective and modal masses of the structure. Here, the required equations describ- ing the dynamic behaviour are first developed and discussed.An analytical vibration system with simulated measurement errors is usedfor demonstrating the identification. In addition, a method to improve the accuracy of the identified parameters is shown.Based on the encouraging results, the application to real test data is en- visaged for further investigations.
