Diagonal Mounting Detail of a Communication Mast.
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 3D CAD geometry followed by an update of the geometry and a new analysis.
The model demonstrates the import of 3D CAD assemblies into COMSOL Multiphysics from a file and through a live connection to the SolidWorks CAD software. This model also demonstrates the individual meshing of parts with the interactive meshing tool.
