Research on Database Construction and Assembly Path Planning Method for Key Components of Phased Array Antennas

Compared with traditional antennas, phased array antennas with key structural components such as multi Vilvadi oscillators and grid plates have advantages such as high gain and high directional ability. Due to the need for a large number of structural components in phased array antennas, this will affect the performance and assembly accuracy of the assembled antenna. How to quickly and reasonably provide an assembly error distribution plan is the key to improving the performance of phased array antennas. This paper proposes a database based on geometric feature extraction of contact surfaces and finite element analysis of contact stress to obtain an optimized assembly plan for key components of phased array antennas, which requires the use of a large number of key components. Considering the real-time updated assembly data, a reasonable assembly path planning method was planned to avoid assembly interference. The simulation results show that this method can significantly improve assembly efficiency and provide a reasonable assembly error distribution scheme.
