Abstract
Abstract
The object of the study was a composite spatial rod structure of cylindrical shape with a coating in the form of a truncated cone. The cylindrical part of this structure was a regularly ordered rod lattice formed of flat regular hexagons. Blocks including linear and rotary springs were used to connect the rods of the polygons. The conical cover was a conventional frame-truss structure. The purpose of the study was to numerically analyze the stress-strain state of a spatial core structure under dynamic influence, taking into account the malleability of nodal connections. The finite element method in the form of a displacement method is used as a mathematical apparatus. Computational experiments have made it possible to design the design of the block for the nodal connection of the lattice rods. Using a full-scale model that included three sections of the grid, the kinematic parameters of the designed block of the nodal connection of the rods were studied.
