Abstract

There were a lot of research on the error truncation analysis of the damping system. However, the theoretical methods that in the analysis of vibration structure and dynamic response are complex and diversified, and there is no completely unified theoretical standard. The main contents of this paper are to summarize the modal analysis methods of predecessors and then divide the methods into the categories from the perspective of error control. Finally, we will make effective corrections on the problem of control error terms in the damping system. In this paper, we will compare the modal superposition theory and method mentioned by the previous ones, so that we can put forward the limitations of each method which is that the analysis method involves only the complex modal solution technique of the general damping system. Therefore it is necessary to study the high efficiency of the damping system (Eigenvalues and eigenvectors). For the complex modal solution of complex damping system, the predecessors use the matrix diagonalization method generally, but there are many restrictions in the diagonalization of the matrix, therefore we can use Jordan Standard-shaped research to start a more general practice and theoretical methods In the case of the more general diagonal solution. Finally, we will prove that the improved method has some restriction on the cut off of control error by numerical simulation.
