摘要
Abstract
The impact method was adopted to identify the fundamental frequency of the satellite antenna, the fundamental frequencies of the structure were gained under three boundary conditions. Test result shows: the fundamental frequency can change with the different boundary condition, but the mode shape and the damping ratio cann't change. The test result could be considered as reference to improve design of the satellite antenna structures.关键词
