ABSTRACT
In order to analyze the influence of noise environment on the structural performance of airborne equipment, this paper presents an investigation on the application of structural noise bearing capability analysis method in airborne radar equipment. In this investigation, a method for analyzing the structural noise bearing capability is introduced, which could convert the acoustic excitation load to the structural random vibration load. Based on this method, the transformation of noise spectrum into the sound pressure power spectrum density is realized. Additionally, the structural performance of airborne radar equipment under noise environment is analyzed by finite element simulation, and the feasibility of applying the structural noise bearing capability analysis method in airborne radar equipment is verified. This study has certain significance in engineering practice for the analysis of noise environment adaptability of equipment.
