Abstract:
A passive compliant non-cooperative target capture mechanism is designed to maintain the non-cooperative target on-orbit. When the relative position between capture mechanism and satellite is confirmed, a pair of four-bar linkages lock the docking ring, which is used for connecting the satellite and the rocket. The mathematical model of capture mechanism and capture space is built by the Denavit-Hartenberg(D-H) method, and the torque of each joint is analyzed by the Lagrange dynamic equation. Besides, the capture condition and the torque of every joint under different capture conditions are analyzed by simulation in MSC. Adams. The results indicate that the mechanism can capture the non-cooperative target satellite in a wide range. During the process of capture, the passive compliant mechanism at the bottom can increase capture space, thereby reducing the difficulty and enhance stability of the capture.
