| Abstract: | Dynamic analysis of the antenna servo system of an airborne radar is carried out in this article. First of all, the finite element model is constructed according to the structure characteristics of antenna and servo unit. Then dynamic analysis such as modal analysis, transient response analysis, frequency response analysis, random vibration analysis are performed using Patran/ Nastran in order to evaluate the dynamic property of the system comprehensively. Analysis result of the article provides critical reference for future structure design optimization and dynamic design. |
