The Structural Design And Mechanics Analysis Of Antenna Mast Of The Navigational Set In Airport

The antenna system mainly is used in vehicle loading system and wireless communication on the ground, navigation and observation and controlling system, is the equipment that receives and transmites informations . The antenna iron is the core part that supports and elevates the antenna equipment. Along with the development of the microwave communication, the radio observation and control equipment,it needs each kind of altitude and loading capacity antenna iron to supporte antenna system , the usual antenna iron is designed by the loading , the wind resistant ability and so on. Its structuralism size of inside diameter, and the outer diameter is determined by the size of installing position space or the experiences.The structural designs not only needs to satisfy the intensity, the rigidity and the service life which the conventional designs have, but also considered from the reliability and the security. The antenna iron should have a big remainder at the intensity, the rigidity and the service life in the structural design. The improvement of antenna structure design method and the mechanical analysis to it is advantageous to enhances the performance of the antenna equipment, lengthens the service life and increases its security.This article design the antenna that be supported by sphere foundation and stabled by the rope according to locating of the antenna on the airport directional beacon and antenna height request, antenna electricity performance and airport equipment and so on.It has carried on the analysis comparison on the structure and dynamics analysis, and has chosen the optimized plan. Because this antenna iron is in hot and damp air and coast, so we decided used stainless steel material(4Cr13)that it has high mechanical strength and the corrosion resistance performance surpassed the aluminum, the rope selects φ 6mm galvanized wire rope. Dynamics analysis include the static load function under intensity,the rigidity computation, the moving load intensity, the rigidity computation under the...
