| Abstract: | In the docking process of medium and small spacecrafts, it is feasible to implement good buffering by docking probe, so that the configuration of docking probe is changed to enhance its deformation capacity and achieve the buffering characteristics of docking impact. By combining Pro/ENGINEER with MSC Patran and MSC Dytran, the modeling is performed on three kinds of probes including cylindrical straight probe, bow probe and spherical probe, the buffering characteristics are simulated and analyzed under frontal collision and oblique collision, and the effect of initial conditions on buffering characteristics is discussed by changing initial relative velocity of collision. The probes with better deformation capacity can improve the buffering characteristics in the docking process and the probes with good deformation capacity perform good adaption to the change of initial conditions. |
