Using finite element software ADINA, three coupling models on fluid-structure interaction among internal fluid—pipe—external fluid in the lifting pipeline were researched. Firstly, coupling finite element model on fluid structure interaction of lifting pipeline was established and the first sixth order natural frequencies and principal vibration modes were attained at different ore conveying volume concentration and cross-section size of pipeline;Then natural frequencies of three couplings were compared with two couplings and no coupling according to the above condition, and FSI effect on natural frequency of pipeline was discussed. The calculation results were shown that the natural frequency of the pipe and its relative error reduced with the volume concentration and the relative wall thickness increased, which explain the reason that has better accuracy considering three couplings than other .These results have certain directive significance on the dynamic response, structure design and study of reduction vibration of lifting pipeline.

Based on the basic principle of fluid-structure interaction, this paper make a finite element analysis of seismic on upper water tank of HPR1000 outer containment by CEL method in ABAQUS software. Firstly, structure is simulated the by Lagrange grid and the water in upper water tank by Eulerian grid; secondly, coupling contact between water and structure is defined; finally, the calculation results are got by running an explicit dynamic solver to makes a time history analysis of fluid-structure interaction finite element model under the seismic, and the results will be used in the structure design of outer containment and upper water tank.
