With the increasing demand and complexity of spacecraft on-orbit tasks, higher requirements are put forward for the dynamic behavior prediction of spacecraft attachment structures. It is difficult to analyze some models effectively by traditional dynamic analysis methods. This paper analyzes the structure of the spacecraft rod antenna and combines the Kane dynamics method, lists the dynamic equations of the Kane form, compares the difference between the Kane method and the traditional modeling method, and draws Kane. The method can calculate and analyze the dynamic stiffening problem. The two models are solved by MATLAB. It is concluded that the dynamic model established by Kane method has more accurate conclusion than the traditional method.
