Abstract
Deployable structure is widely applied in the space large antennas because of the limitation of the size of the launch vehicle fairing and the low stiffness of the launch antenna.Deployable structure can be folded at the time of launch, and be deployed while reaching the specified location, and then maintain a certain working configuration.However, when the deployable structure works, it will be inevitably disturbed by the speed, which will further affect its accuracy.Therefore, this paper tries to describe the deployable structure based on the method of absolute nodal coordinate, and conduct the programming by using the Newmark numerical method based on the structural dynamic equation.By analyzing its structural dynamic response for velocity disturbance, the response curve was obtained.The research results are of great practical significance to the analysis of dynamics control.关键词
