METHOD TO TEST MULTI-LINK MECHANICAL SYSTEM OF SPACECRAFT FOR FUNCTIONING AND DEVICE FOR ITS REALISATION Russian patent published in 2014 - IPC B64G5/00 B64G7/00 G01M17/00 

FIELD: testing equipment.

SUBSTANCE: invention relates to ground imitation tests of spacecrafts (SC), and namely to multi-link low-stiffness mechanical systems of space equipment items. The device of weightlessness of a multi-link mechanical system of SC comprises rotary sections fixed on SC, arranged in plan above the appropriate links of the mechanical system and connected to them by means of controlled springs of weightlessness, a transformable support structure from horizontal bearing rods with brackets, rotary sections. The bearing rod least distant from the SC is fixed on the SC, and the bearing rod most distant from the SC by means of the support stand rests onto the premise floor. The transformable support structure is equipped with fixators of mutual position of bearing rods, bearing rods are equipped with L-shaped supports, resting against premise floor, brackets are placed onto bearing rods as capable of interaction and fixation with rotary sections in their ends most distant from the spacecraft. The SC with a fixed device for weightlessness of the multi-link mechanical system is installed in place of test performance, they perform installation and fixation of the required configuration of the support transformable design in the horizontal plane, serially fixing the positions of the rotary sections of the weightlessness system in the horizontal plane.

EFFECT: invention makes it possible to increase functional and operating characteristics of devices for tests of multi-link low-stiffness mechanical systems of space equipment items.
