The basic status of 65 m antenna structure is introduced and the basic matrix equations of FEA with load and boundary conditions for of 65 m antenna are analyzed.With the statics analysis and dynamics analysis of the 65 m antenna,the resonance frequencies and accuracy of antenna structure at typical elevation angles are obtained.Meanwhile,with the strength analysis of antenna,the strength safety coefficients of antenna structure at different elevation angles and operating conditions are obtained.With the results,a conclusion is drawn,that the antenna structure would meet designed requirements at given conditions,and breakage would not occur.This conclusion provides warrant for structure design of the project.
