A model updating method considering the complex mechanical environment

By Jinwu Xiang, Shiwei Zhao and Daochun Li

Abstract

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
