摘要：
Resonance mode analysis based on eigenvalue decomposition is a very computing-intensive work in the frequency scan process. This letter presents a modified power iteration method for modal analysis to reduce the computing time. Simulation results verify that the proposed method possesses a faster computing speed by evidently eliminating the unnecessary iteration numbers.
