英文摘要：

The geometrical continuity conditions in the interfaces of substructures have a significant influence on the accuracy of the solution of the substructure synthesis method. In this paper, some strategies for dealing with the problem using the reduction and non-reduction models in the system structure are investigated and applied to predict the vibration characteristics of a cylindrical shell structure. The feasibility of the strategies is discussed. Comparison between the vibration response predictions and the experimental results slhows that the proposed method for dealing with the boundary conditions of the substructures is valid, and can be applied to study engineering problems.
