Dynamic Analysis of Extendible Support Structure Deployment
To study the dynamic behavior of the extendible support structure deployment,a digital simulation using the multibody system dynamics methodology is conducted.Floating frame of reference formulations are used to establish the flexible dynamics model,in which the deformation vector of each flexible part is modeled with the component mode synthesis technique based on the Craig-Bampton method.Modal truncation is implemented through modal participation factors to reduce the computational burden.Angular displacements results of antenna panels as well as those of truss rods are then obtained and show that all parts of the structure have reached accurate positions and keep stable after deployment as expected.Start torque of the driving motor is also acquired and proved acceptable according to the design requirements.Impact forces acting on the hinges at locking moment are finally extracted to evaluate performances of locking processes.
