Study on the Dynamic Response of the Solar Panel Adsorption Device to the Satellite System During the Attachment Process

In recent years, the study of on-orbit manipulation and service of spacecraft has received increasing attention, among which, the attached manipulation of non-cooperative space targets is one of the research hotspots. This type of adsorption device generally attached to a target spacecraft by attaching to the solar panel. The impact on the solar sail panels during attachment causes a significant dynamic response of the entire system, which may cause problems such as adsorption device falling off, resulting in mission failure. In this paper, we investigate the dynamic response of the target system during attachment. The target system is simplified to a hub-beam structure. The governing equations of the system are derived based on Hamiltonian Principle. A three-dimensional finite element model was established based on Ls-dyna software, and the dynamic analysis was carried out, which is mutually verified with the theoretical analysis. Based on the FEM, the influence of different adsorption device’s attachment position on the dynamic response of the target system is studied. The research results can provide a theoretical basis for the selection of attachment position of the adsorption device.
