Research On The Bearing Mechanism And Spring Element Numerical Simulation Of The Bed Seated Large-diameter Cylinder Structure

Numerical simulation of bed seated large diameter cylinder structure is put forward as a research cut-in point. The FEM model used spring element to simulate the reaction between the structure and foundation is established,by using software ANSYS .The major work can be summarized as follows:1.Basis on the collected and simplified bed seated large diameter cylinder structure trial data, researches on the mechanism and load distributing of this structure are made,and a new elastic spring element numerical analysis method is put forward.2.For the complexity of the cylinder structure, the analysis of the stability and intensity is complicated, combined with engineering practice, a simplified numerical model is established, and the distributing of stress and silo pressure are discussed.3.Based on the Winker foundation model theory, using software ANSYS, a new elastic spring element numerical model to simulate the reaction between the structure and foundation is established . according to a practical engineering example, the feasibility and validity of this model is verified by contradistinctive analysis with joint element.4.Some correlative conclusion are obtained. And some relevant opinions and suggests is put forward about bed seated large cylinder structure.
