| Abstract: | A stability identification method of numerical integration for multi-DOF systems is suggested in this paper based on the modal analysis method.As examples the Euler backward difference method, the Newmark method and the Houbolt method are discussed to describe this stability identification method, and some useful results are obtained for choosing some appropriate numerical difference formats. |
