Analysis of a Structural Integrity Submarine Navigation Radar Antenna Device based on One-way FSI Analysis

Submarine navigation radar is an essential equipment for detecting and tracking surface targets during a submarine’s surface or periscope navigation. Given the characteristics of a submarine, the installed equipment must be structurally robust with respect to external forces in surface and underwater conditions. In this study, a finite element analysis model was developed to analyze the structural integrin, and wind and fluid drag were selected as the main loads by considering the surface and underwater conditions. Finally, stress-based evaluation of the structure were performed based on the results of one way FSI analysis to evaluate the structural integrity of the navigation radar.
