of the longitudinal and transverse shock absorbers cease Tn the transition from docking of two identical spacecraft to docking of this spacecraft with a “heavy'' station Io may increase by a large factor (for example, in the docking of the Soyuz and the Salyut station, increases by about a factor of six compared with the docking of two Soyuz craft). Due to this change in the applied moment of inertia, it became necessary to substantially increase the energy capacity of the angular shock absorbers in the Soyuz-Salyut docking device, compared with the Soyuz docking mechanism. The angular shock absorbers of “rod and cone” docking devices do not actuate after rotation of the spacecraft until the supports on the docking mechanism touch the cone . The rod of the docking mechanism rotates by a small angle during shock absorption . Thus, the approximated analysis using (5.7) may be done for a constant value of calculated for As analysis has shown for spacecraft for which that the increase in angular velocity due to longitudinal momentum may be significant (for the docking of two Soyuz; for the docking of spacecraft with widely different characteristics this increase is smaller (for the docking of a Soyuz spacecraft and a Salyut station . As a result, the
