In this paper, dynamic behavior of docking mechanism during its acquisition period is analyzed. The results show that the docking mechanism can be modeled as a six-freedom rigid body with a flexible support during this period, i.e. a typical structure. Because there exists nonlinear characteristics due to spacing, retardation, and friction in transmission elements and elements themselves, the theoretical analysis shows that docking mechanism can be simplified as a linear system and its dynamic characteristics determined through testing-spectral function recognition method based on the linear vibration theory and corresponding software, after weakening effects of nonlinear factors. In order to determine whether docking mechanism has basic characteristics of a linear structure, some experiments have been carried out. The results show that testing-spectral function recognition method can be used in dynamic systems.
