METHOD FOR TESTING OF SPACECRAFT EQUIPMENT BY MECHANICAL ACTIONS Russian patent published in 2009 - IPC G01M7/02 

FIELD: physics, tests.

SUBSTANCE: invention is related to the field of tests and may be used in tryout and acceptance tests of SC. Method consists in vibration loading of equipment at previously set modes with further inspection of tested equipment serviceability. Besides tests are carried out in several stages: at first minimum value of own frequency is detected for accessories with equipment, then test mode is generated for wideband accidental vibration in pre-resonance area of accessories, and equipment is loaded with generated effect. Then equipment is installed on honeycomb panel, lowest own frequencies of which are located in pre-resonance area of accessories, and honeycomb panel is installed with equipment into acoustic chamber, afterwards honeycomb panel with equipment is exposed to acoustic loading in specified frequency range starting from frequency that is lower than lowest own frequency of accessories. Moreover, acoustic loading is increased stepwise from minimum value, at which wideband accidental vibration appearance on honeycomb panel is registered, to the level of acoustic loading, which provides for specified mode of wideband accidental vibration.

EFFECT: simplified procedure of tests performance.
