One of the capabilities of MAGSA Knowledge-Based Company is the design of sensitive structures holding aerial antennas. The sensitivity of these antennas is such that due to strong winds, there should not be the slightest movement in the antenna support. This supporting structure is capable of withstanding wind speeds of up to 160 km / h as well as loads of 11 kN with high reliability. To simulate this antenna, computational fluid dynamics( CFD) and FSI has been used to determine the load. After determining the natural frequencies of the supporting structure using modal analysis, you compared the results with the frequency of the vortex falling behind the structure, so that the predictions about the absence of resonance in the structure are considered. After determining the wind load and other forces entering the structure to determine the amount of deformation and stress, static simulation was performed.
