Abstract: Based on the Lagrange theory in the Euclidean space, the semi-inverse method was proposed to solve mechanical problems in the past several centuries, which depends on the specific situation resulting in narrow applicability. As a reasonable structure-preserving method, symplectic geometry method of Hamilton system can preserve some geometric properties of the systems, such as: energy conservation、symplectic structure and first integral. For long time simulation, Symplectic geometry method is more stable and precise than traditional method. In this talk, we focus on the following tree aspects:

1) Symplectic method for the middle thickness plate on Winkler elastic foundation.

2) Structure preserving analysis method for the oscillator system,

3) Steady-state solution to the infinite dimensional Hamilton system.
