This study deals with the structural safety analysis of large radar structures with elevation drive units. Large radar is an essential military equipment that detects the trajectory of the shell, tracks the launch point, and neutralizes the enemy weapon. A large radar is equipped above the military vehicles, with an elevation drive unit that can elevate quickly to detect shell trajectories at a desired position. However, large radars with elevation drive units are affected by various external forces depending on the angle of elevation and transportation environment. Furthermore, elevation drive units that control the angle of elevation are vulnerable to buckling. Large radar structures require high reliability of structural safety under various conditions for operation. This study analyzes the structural safety of a large radar structure with respect to the drive angle and external forces using finite element analysis. For this purpose, buckling safety of the elevation drive unit and main component stresses are analyzed. The results of the analysis showed that the large radar was structurally safe against stresses and buckling caused by external forces at various angles of inclination. In addition, it is structurally safe with respect to the random vibration PSD(power spectral density) during radar transportation.
