[Abstract]:Aiming at a series of new problems in antenna measurement technology, such as the increase of antenna size and weight and the improvement of precision, according to the design requirements of a certain type of radar antenna test turntable system in Shanghai Aerospace Electronic Communication Technology Research Institute, In this paper, the structural parameters of the antenna test turntable are optimized, and its control performance is analyzed and studied. The main work of this paper is as follows: 1) combining with the development project of the test turntable system, according to the technical specifications and functional requirements, In this paper, the overall structure scheme of the antenna test turntable is discussed in detail, and the feasibility of the scheme is demonstrated. The mechanism of the antenna test turntable system is designed and verified, and the strength and reliability of the key components are calculated. The finite element simulation is used to analyze the stress situation of the limit position, to check and verify the strength, material selection, safety and reliability of the important moving parts of the antenna test turntable. The performance of the antenna test turntable servo control system is analyzed, the control strategy, the selection and design of each component of the system are studied. The dynamic model of antenna test turntable is established, and its system dynamics is simulated and analyzed by ADAMS, which verifies that the antenna test turntable works normally. The force of the related components and the performance of the selected motor reach the dynamic performance required by the antenna test turntable. The research content of this paper has certain guidance and reference value for the design of large size, heavy quality and high precision antenna test turntable.
