| Abstract: | A simplified dynamic model of a dish antenna in satellite is established in this article.The model can be easily used to analyze the dynamic behaviour of the antenna structure.In terms of the simplified model,effects on dynamic characters due to the disorder of parameters are investigated in details.The frequencies calculated by the simplified model accord with those computed by ANSYS.Based on the mode shapes of disordered and perfect structure,the influence law and varying trend of dynamic characters of an... |
