【 摘 要 】

As a new method of application usage of cabin, the experience design combines with finite element simulation during the development process is effective. This method can quickly determine the rationality of the design and effectively shorten the development cycle. According to the layout features of a certain type of antenna cabin, the stiffness of the roof structure was enhanced, so that the local stiffness was improved, but the total stiffness declined after the cabin raised. The antenna produces periodic dynamic load when working, the natural frequency of the cabin should avoid antenna working frequency in order to avoid resonance. The natural frequency of the cabin was analyzed by finite element method, according to the typical condition. The structure of the cabin was simplified when the finite element modeling. The results show that the natural frequency of the cabin avoids antenna working frequency, and the rationality of structural design was verified.
