| Abstract: | Basing on the variation principle of solid-fluid coupled problem,on the situation of the tank being full filled,the essential method and principle have been found by using the numerical approximation of finite element method.And the complex solid fluid coupled dynamics equation of railroad tank is established.The influence by liquid to the solid-fluid coupled tanker is conformed,and we also obtain the results which are needing in the project. |
