The Schur subspace iteration method is applied for the dynamic characteristic analysis of damped structure vibration system and coupled fluid-structure system. This method avoids complex computation and has good numerical stability. A accelerated technique and a pre-process method for the system matrix are suggested to improve the computational efficiency. The generalized uncoupled equation is obtained from the Schur matrix and a back substitution scheme of response computaton is developed.

The forth algorithm is the same as the third one with an addition of finite termination criteria. Although the latter two algorithms have only linear rate of convergence, they are especially suitable for large-scale and sparse problems, with features of simple formula, small storage, sparsity preservation and easy implementation.
