ドッキングダイナミクスシミュレータの開発

抄録

To evaluate the performances of the autonomous Rendezvous and Docking system, a hybrid docking dynamics simulator was developed. The relative motion of the spacecraft after collision was realized in a real time by a computer-controlled moving table on which real docking hardwares were exposed to the target. The mechanical configuration, computer architecture and the simulation algorithms are described. To make the system faithful, the stability of the oscillation casued by the mechanical connection between the spacecraft is analyzed. Then the stability augmenting compensation whose validity is proved by the experiments is introduced. Several docking tests prove the simulator to be a powerful tool for developing docking systems.
