had to increase on the Soyuz to 1.5 kN or to 2.6 kN on the Apollo to guarantee linkage of the spacecraft at any approach velocity. 5.6.4. Other Forms of Interaction Before Linkage 1. The interaction of the guides with the ring. This case is analogous to impact with the cone in the “rod and cone'' docking device. Just as in the impact of rings, the transverse and angular shock absorbers operate; however, here the geometry of the surfaces at the point of interaction determine the direction of the force. For constant slippage for the two-dimensional case (Figure 5.21) friction may be considered. The equations of deformation of the shock absorbers have the form The values of the radii and and the angles and fl2 depend on the position of the point of interaction along the guides. As a result of the calculation, the following are defined: force, course of transverse and angular shock absorbers for maximum velocities, and coefficient of recovery. 2. Impact of guides. This case requires a three-dimensional model and all six
