RESEARCH OF THE INFLUENCE OF THE GEOMETRY OF ORTHOGONAL RODS PLATES ON THEIR STRESS-STRAIN STATE

Cover Page

Abstract


In this work is studied the effect of the geometry of the rods plates on their stress-strain state. The rods plates with the cubic and pyramidal shape of the cell are considered in order to obtain the dependences of internal forces, deformations and frequencies of natural oscillations on the height of the plate and the aspect ratio of the plate. Spatial design schemes with a variation of the cell shape, the height of the plate, and the aspect ratio have been constructed. A static design is made of the unit load applied to the upper grid and the modal analysis. The values of the forces in the elements, the displacement of the nodes, the frequency and the shape of the natural oscillations are obtained. The graphs describing the dynamics of the stress-strain state change depending on the influencing factors are constructed.
