Stiffness Analysis of a Communication Mast´s Diagonal Mounting
Model ID: 1363
Communication masts usually have a framework with a bolted triangular lattice design. The diagonals of the framework are assembled from several parts and welded together.
When operating under a given wind load at a specific location, the antenna’s total rotation angle should stay below a certain limit to ensure uninterrupted communications. For the type of mast in this model, the engineers have determined that its torsional stiffness is too low, and this effect is due to the geometry of the diagonal mountings. The goal is to increase the stiffness of such a diagonal mounting by first analyzing an existing geometry followed by an update of the geometry and a new analysis.
The model also demonstrates the individual meshing of parts with the interactive meshing tool.
