Complex approach to mechanical tests of executive automatic units of space vehicles

The problem of qualification of space vehicle units according to their resistance to mechanical influences is examined. For units having elements with a low natural frequency, an approach supplementing independent tests by the dynamic analysis in view of the way of their integration into a design of a space vehicle is proposed. The result of the dynamic analysis is confirmed by testing the units in the case under consideration the equaliser of volume in an active thermal control system, in the structure of a space vehicle model for dynamic tests, and the content of the program of independent tests of such a unit is established on the basis of the given approach.
