Lightweight design of ship phased array radar structure by integrating finite element model and size optimization algorithm

With the rapid development of computer technology and artificial intelligence, the lightweight structure of ship phased array radar has become the key to improving its maneuverability and endurance. In order to improve the lightweight effect of the ship phased array radar structure, a finite element model ship phased array radar topological structure optimization method based on the variable density method is studied and proposed for the efficient modeling and solution of structural lightweight. In addition, the research also proposes an ant colony algorithm with improved adaptive factors for the size optimization of phased array radar structures. In the simulation test experiment, the reaction time and memory usage of the proposed algorithm are 33.2ms and 0.30GB respectively. After lightweight size optimization, the ship phased array radar structure has a mass of 340.7kg, a maximum deformation of 3.2mm, and a maximum equivalent stress of 107.9MPa, which is significantly better than the comparison algorithm. The experimental results show that the proposed method has fast response speed, low memory usage, and can make excellent lightweight improvements to the ship phased array radar structure, which provides certain experience and ideas for the development of computer intelligence in lightweight structure.
