FINITE ELEMENT ANALYSIS AND OPTIMAL DESIGN OF A RADAR BLOCK STRUCTURE
Abstract
On the basis of realizing the radar function,the radar base is required to be light and rigid. A radar support base is designed and the load-bearing condition of the structure is analyzed. The finite element method is used to analyze the structure of the radar pedestal,and the strength and deformation of the radar pedestal are obtained. The equivalent stress value of a node is compared with the theoretical calculation results to verify the reliability of the finite element simulation results. According to the results of finite element analysis,the structure of the radar base is improved. Analyze the influence of the size of each component on the quality,maximum stress and maximum deformation,determine the optimization variables,and optimize the radar base structure with multiple objectives. After optimization,the mass of the radar base is reduced,and the mechanical performance is significantly improved. This is the design and optimization of the radar base structure. Provide a theoretical basis.
