基于模型重构的天线机电耦合仿真方法研究
Study on simulation method of antenna electromechanical couplingbased on model reconstruction
摘要
Abstract
Electromechanical coupling involving the interaction of mechanics, electromagnetics and thermotics, which has a direct impact on product's performance.Data transfer between different physical fields is the key to the electromechanical coupling simulation.An method based on model reconstruction to analyze the electromechanical coupling of microwave antenna was presented and a simulation platform was developed.In the simulation platform, firstly, the mechanical analysis was carried out by ANSYS.Secondly, the APDL language was applied to obtain and export the deformed mesh of the structural analysis, and the deformation geometric entities was reconstructed by the Non-Uniform Rational B-Spline (NURBS) theory and deformed mesh.Finally, the deformation entities were imported into the HFSS (electromagnetic field analysis software) to calculate the performance of the deformation of antenna.The waveguide slot antenna was applied to verify the correctness between the method and measurement results.The study shows that the electromechanical coupling will affect the performance of antenna.This method can be used to analyze the electromechanical coupling of antenna at design stage.关键词
