In this paper, we establish a mechanical model of the structural dynamic analysis for the legs of fixed pile leg marine structures, where the hull doesn’t float out of the water. We make a calculation and analysis of the dynamic model by using the finite element analysis software “ABAQUS”. Also the cushioning mechanism of different materials is analyzed. Accordingly we establish a dynamic analysis model of a cushioning system. An elastic modulus linear model is used to simulate rubber materials, in order to carry out a qualitative analysis of the cushioning effect of a cushioning device in a reinforcing area. Taking rubber materials’ different elastic modulus and different load impact frequencies as variables, a series of calculation results and analysis are presented. Through a comparative analysis of the different structural dynamic response between the buffered and the non-buffered, we draw the conclusion that the dynamic load of the legs has been effectively alleviated with a cushioning device which is helpful in leg-protection.

The finite element analysis model was built as the real scale for mortar arch framework slope protection, and the displacement and strain at different points were collected by vertical loading pressure. So the mechanical mechanism can be studied, and the analysis was done between calculation results and testing results of solid miniature model. The studying results show that the point on the arch foot is the worst stress place for each arch, and the total displacement increase nonlinear as the distance from the slope top increases, and the bump phenomenon exists in the bottom of slope, the points are likely to be broken.

Story Building

A three-story old building made up of masonry and wood will be retrofitted to be a new 14-story building, retaining two exterior walls and removing all internal members. To prevent the retained walls form deforming severely or collapse during the retrofit is necessary. The finite element analysis software, ANSYS, is used to calculate the responses of the retaining walls under possible loading conditions. The original retrofit proposal for the old building is refined based on the calculation results.

The virtual prototype model of the coal screen is established with Pro/E and RecurDyn based on virtual prototype technology. The kinematic characteristics of different points are obtained by simulation. At the same time, the finite element analysis model of a screen box is established with ANSYS. Modal analysis and harmonic analysis have been carried out based on dynamic analysis technology. According to the results of dynamic finite element simulation, some corresponding improvements were made for the structure of screen box, which makes the stress concentration region of screen box decreased and more uniform stress distribution to meet the design requirements.
