AbstractAs the accuracy and stability requirements of space structures increase, structural microvibration has become a critical problem. However the measurement of the in-obit microvibration is difficult and costly compared to the measurement on the ground. It’s essential to establish the relationship between the ground test data and in-obit microvibration. In this paper, a model updating method is established to predict the in-orbit microvibration model using the ground test data. A numerical example of a satellite model is presented to validate the model updating method
