Optimisation Design of Large-Scale Shipborne Radar Structure Under Complicated Load Conditions

Дата публикации: 01-01-2027 00:00:00

In the design of large-scale shipborne radar structures, it is necessary to consider the influence of various types of environmental loads such as strong wind, ship rocking, and high/low temperatures on the strength, safety, and deformation accuracy of the whole equip. Based on the theory of computational fluid dynamics and elastic mechanics, the comprehensive load condition of a certain type of shipborne radar under strong wind conditions is simplified by the decoupling analysis method, the evolution characteristics of the flow field and drag analysis are examined by CFD numerical simulation with the hybrid turbulence model, the overall structure of the radar is optimised, the force deformation of the main structure of the radar is analysed by combining the step-by-step simulation and simplified modelling method, and the dynamic response of the radar structure is analysed by combining the characteristics of wind pressure ripple frequency.
