Abstract: Non-linear dynamic behaviors of spacecraft joint-dominated structure affect spacecraft modeling, attitude control and pointing precision. This paper introduces advancement in local non-linearity, non-linear vibration of structure, normal non-linear modal and model reduction. Finally, some advices about future development in this field are given.
