| Abstract: |
| The work aims to optimize the traditional experience-based shipborne radar structure design process, shorten the design cycle and improve the design accuracy.A new design process based on modal analysis and PSD method was proposed. Radar antennas and turntable structures were analyzed by ANSYS software for systematic random vibration analysis. The modal cloud map, stress distribution cloud map, displacement cloud map and response spectrum curve were obtained to verify the design accuracy and reasonableness. The maximum stress value and maximum deformation of the radar system at 1σ were 14.847Mpa and 0.367mm, respectively. The new design process can get more reliable products. It can effectively shorten the product design cycle and has important reference significance. |
