METHOD OF TESTING SPACECRAFT MULTI-MEMBER MECHANICAL SYSTEM FOR FUNCTIONING AND DEVICE FOR REALIZATION OF THIS METHOD Russian patent published in 2007 - IPC G01M13/02 G01M19/00 

FIELD: testing technology; testing of multi-member mechanical systems for functioning during ground optimization of structures.

SUBSTANCE: proposed method includes securing of each member of mechanical system to respective section of beam system supporting the mechanical system by means of adjustable springs for opening of mechanical system in vertical plane. Then, members of mechanical system are unweighed through adjustment of springs and each member of mechanical system is rigidly connected with respective section of beam system. Tests are conducted at simultaneous opening of members of multi-member mechanical system and section of beam system, thus checking the mechanical system for proper functioning. Device proposed for realization of this method is made in form of ring secured in upper part of spacecraft and provided with sectionalized swivel rods. Sections of sectionalized swivel rods are located in plan above respective members of multi-member mechanical system and are connected with them by means of adjustable unweighing springs and adjustable rods consisting of bars and bushes. Adjustable rods are located symmetrically on both sides from respective adjustable unweighing spring.

EFFECT: enhanced accuracy of test results; possibility of keeping multi-member system intact.
