Structure Improvement and Mechanical Analysis on Data Transmission Antenna
Data transmission antenna plays an important role in transmitting data from satellite.The structure of antenna consists of four parts,including a feed tube,a reflecting surface,a brace and a adapter.Due to the unreasonable structure design and coarse mechanical analysis,the initial data transmission antenna was broken at the comer of a spiral in the process of random vibration test.In this paper an improvable method is brought up and mechanical analysis is carried out,the result shows that the first frequency raises from 324Hz to 328Hz and the stress root mean square decreases from 62MPa to 37MPa in X-direction random vibration.Of course,the improved antenna passes the random test.
