摘要
Abstract
A study is taken on modal test of a large deployable support beam with low frequency and non-linear vibration response characteristics. The locations of shaker and sensors are got by finite element method and the support beam modal test is actualized with different methods. The 1st to 6th natural frequencies, modal dampings and vibration modes are obtained through detailed analysis of the test results. The test results are comparatively analyzed with finite element meth- od. It is proved that the test results are reliable. The research results are essential to the modal test of solar wings and deployable antennas too.关键词
