Model Considering the Inertia of the Shock Absorbers The mass of the ring with guides of peripheral docking devices and the masses of the moving elements of the attached shock absorbers are relatively large; thus, in the interactions of the rings additional significant dynamic forces arise. Thus, it is expedient to develop and use mathematical models which consider the forces of inertia of the buffer and shock absorbing elements. It is necessary to consider the deformation of contacting parts [32]. The motion of the “inertial” ring is due to the effect of interaction reactions with the passive docking assembly and the force of the shock absorbers . The value of the reactions can be calculated by introducing the
