An enhanced computational approach for multi-physics coupling analysis of active phased array antenna
An enhanced computational approach is formulated to assess the service performance of active phased array antenna (APAA). For this approach, the discretized system equation of the thermo-mechanical coupling analysis is firstly constructed by the node-based gradient smoothing technique. Then, the stabilization terms are introduced to further improve the computational accuracy and stability, which are related to the temperature and strain gradient of APAA. Finally, the thermo-mechanical-electromagnetic (TME) coupling model is established by quantitatively analyzing the relationship between electromagnetic performance and thermal deformation of APAA. The accuracy, efficiency, convergence speed and mesh distortion insensitivity of the developed approach are deeply studied and its effectiveness in addressing the multi-physics coupling analysis of APAA is fully demonstrated through comparisons with traditional methods.
