Abstract

In order to solve the problem of lacking the corresponding magnetic torque resolution model in the design process of permanent magnet type mechanical antenna，this thesis discusses the basic form of antenna array and establishes the magnetic torque model for hetero-axial linear mechanical antenna array, derives the time-varying curve of magnetic torque during rotation, verifies the accuracy of the torque model through simulation, and analyzes the relationship between magnetic torque and permanent magnet spacing and permanent magnet magnetization direction. It is concluded that in order to reduce the torque required to drive the antenna, the inter-magnet torque should be increased, and when selecting the permanent magnets, the permanent magnets with the magnetization direction along the shortest side should be selected for the same volume case. The analytical model provides theoretical support for the design and optimization of the structure of the permanent magnet type mechanical antenna array.
