Problems solved by technology

However, these analysis methods do not take into account the manufacturing errors that must exist in the actual processing of the antenna, the random errors determined by the installation and debugging accuracy, and the systematic errors generated under the action of external loads, so that these analysis methods are only applicable to the analysis of ideal models. The accuracy and efficiency of its analysis are also restricted, and it is difficult to improve

Abstract

The invention discloses a comprehensive electromechanical analysis method of a reflector antenna based on error factors, which is used for solving the problems that unsatisfactory models can not be analyzed and manufacture errors, random errors, and system errors in the analysis process can not be implemented with the traditional analysis method. The comprehensive electromechanical analysis method comprises the following steps of blending the manufacture errors into structural parameters for carrying out geometric modeling; implementing environmental load, controlling the system errors, and accomplishing structure analysis to obtain a transformed structure model; transforming the transformed structure model to an electromagnetism analyzing model by model transformation; and carrying out electromagnetic analysis to obtain the electrical performance of the reflector antenna. The comprehensive electromechanical analysis of the reflector antenna can be finally realized by the system analysis flow of the method. With the method, the manufacture errors, the system errors and the random errors are introduced into the antenna analysis process and the analysis precision and efficiency of the antenna are obviously enhanced, and the method can be used in the analysis and the design work of a microwave frequency band reflector antenna, a planar slot array antenna and a filter.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to an electromechanical comprehensive analysis method of a reflector antenna, which is used for improving the analysis accuracy and efficiency of the reflector antenna. Background technique [0002] The reflector antenna is a typical electromechanical integrated electronic equipment product. As it develops in the direction of high frequency band, high gain, high reliability and lightweight, the interaction and mutual influence between its structural displacement field and electromagnetic field becomes more and more obvious. , due to the unclear relationship between the two fields, the improvement of the electrical performance of the antenna is greatly restricted. Therefore, it is necessary to deeply study the relationship between the two fields and realize the electromechanical comprehensive analysis of the reflector antenna. In the traditional analysis method usi...
