Abstract

In this paper, the equivalent mechanical spring model of the three-dimensional continuumis studied. And the sectional area of the equivalent spring element is obtained based on the displacement equivalent principle. The equivalent model is statically indeterminate trusses system of spring. The 3D spring calculation model can be used in the static characteristic analysis. By using equivalent spring element model as the basic unit of analysis of a triangle continuum static analysis problems, and with the use of triangle constant element as basic element income results were compared. The results show that the simplified form in good agreement with the exact solution, the establishment of the equivalent, and compared with the commonly used continuous medium finite element model, computational efficiency and accuracy of equivalent spring element model is higher. It shows that the equivalent spring model have theequivalent stiffness in the static analysis.
