Dynamic Model Updating of Satellite Structure Using Vibration Test Data

Abstract

This paper presents the model updating technique for satellite structure by using the vibration environment test data. In the paper, several key technique issues related to the model updating of satellite structure, such as selection of updating parameters, model reduction, damping identification, etc, have been discussed. As an example, the model updating for a satellite central cylinder structure using the shaker vibration environment test results is described. It is proved that the techniques presented are effective for engineering applications.
