Abstract

The article provides a description of the developed method, which ensures the correct realization of mechanical tests of on-board radio-electronic equipment of spacecrafts for vibration effects in the process of ground experimental testing. Since in the process of vibration effects, resonance phenomena arise, which can cause effects on the elements of on-board equipment hundreds of times higher than the normalized levels of effects, which occur under normal conditions at the time of launching the spacecraft into the target orbit. In this regard, during the testing process, the failure of test objects systematically occurred, caused by unreasonable levels of impacts due to emerging resonance phenomena. In order to solve the problem of realization mechanical tests for vibration effects, a method of “cutting frequencies” in the resonance region was developed. The developed method in general is a process of determining the quality factor of the test object at the time of determining its natural frequency. If resonance phenomena are detected, the driving accelerations are automatically reduced to a value corresponding to the normalized levels of impacts. As a result of technical approbation of the developed method of testing for vibration effects of on-board radio-electronic equipment, its operability was confirmed. The implementation of the developed method made it possible to provide standardized test modes that fully met the specified requirements and confirm the qualifying margin of safety of the manufactured on-board radio-electronic equipment of spacecraft.
