First, eigenvalues and eigenvectors of time-varying system are identified in real time with subspace approach and then, physical parameters at joint in structure are estimated on the basis of the eigen pairs obtained by using substructure method.

In this article based upon analysis of the interaction of superstructure, foundation and piled raft of tube structure the substructure method is introduced in detail; at the same time corresponding fundamental equation is built.

This paper presents a substructure method of static sensitivity analysis of light car white body to simulate the dynamic sensitivity analysis of bus.

The substructure method for scattering by large open-ended cavities

The substructure method was introduced to set up mathematical model of finite periodic composite structure,to solve its wave equation,and to derive its time-average power flows.

The application of the substructure method efficiently solves the combination of finite element and infinite element.
