- W4285243388 abstract "In response to the requirements of lightweight and strong vibration resistance of a large airborne radar antenna, the optimization design of mechanics and the evaluation of dynamic strength were carried out. Based on topology optimization technology and size optimization technology, the mounting bracket and frame were optimized, and the optimal configuration and thickness distribution of the structure were obtained. For the optimized model, comparative analysis and experimental verification of the dynamic structural rigidity were carried out. The results show that the optimized structural model has been significantly improved in terms of structural frequency, dynamic strength, and lightweight level; successfully solved the problem of the original design model's stress intensity and the coupling resonance of the main modal frequency and environmental conditions. Based on the optimized model, the antenna prototype successfully passed the 9-h/axial durability vibration test, and the antenna structure optimization achieved relatively ideal results." @default.
