摘要
Abstract
The flexible vibration frequency of the satellite changes with rotation of the solar wing,it is important to avoid resonance especially in the dynamics frequency planning.In this paper,the flexible dynamics of satellite with rotatable solar wing is researched,and the change of the satellite mode frequencies affected by the configuration variation is studied.Firstly,the hybrid coordinate equations of flexible dynamics of satellite are given to deduct the structural dynamics equations of the whole satellite.Secondly,the characteristis equation of the on-orbit modes is given,then the satellite mode frequencies are solved for every rotational angle of solar wing.Finally,a remote sensing satellite is taken for example to verify the accuracy of the method by compare the on-orbit data with the computing result.关键词
