For experimental verification of the shock absorption of rotation after linkage one can use the horizontal test unit with an addition. Its parameters (mass of the trolley size of lever rP) are chosen from the conditions of equality of the equivalent moment of inertia Io defined by formula (4.28) and the moment of inertia of the load relative to the point of linkage, that is . The rate of acceleration in the verification of the maximum energy capacity of the angular shock absorbers is defined by the maximum rate of rotation after linkage that is, Acceleration of the trolley in horizontal test units is done by a “falling'' load with a cable connection. This load, the mass of which can be changed, is also used to test the loaded drive of the docking mechanism. The test unit is equipped with a system to measure the parameters of displacement, the velocity of the trolley and the rocking load, the force and overloads during impacts, the parameters of operation of the shock absorbers, and other units of the docking mechanism. Testing in the test unit is done in normal conditions. The great complexity of the process of shock absorption in peripheral docking mechanisms, compared with the “rod and cone” device, was the reason for the more complex principal scheme of the test unit to test the APDA (Figure 7.16). To reproduce shock absorption with roll displacements, the trolley of the unit was equipped with an additional load. The moment of inertia of this load is defined by a known formula (see section 5.6.5). On the faceplate of the load is one of the tested APDAs; the second assembly is attached to the adapter of the rocking load. The axis of this load is located in the
