METHOD OF VIBRATION TESTING OF COMMUNICATIONS-ELECTRONICS EQUIPMENT Russian patent published in 2015 - IPC G01M7/00 

FIELD: test engineering.

SUBSTANCE: invention relates to test engineering. The method is implemented as follows. The test product is affected with harmonic vibration reproduced on a shaking table, and which is equivalent to the shock effects arising from the transportation of the product. The parameters of impulse force of harmonic vibration I_hv are determined preliminary by calculations, the determining of impulse force is carried out throughout the frequency range of 5-60 Hz. Then, the received pulses I_hv ≥ I_i are compared, where I_i is impulse force of equivalent impact, with the proximity of the impulse forces, at that the frequency of vibration exposure, at which the impulse force of harmonic vibration I_hv, close to the average value of impulse force of impact, was obtained, corresponding to the condition I_hv ≥ I_i, is taken as the frequency at which the test for transportation is carried out.

EFFECT: ability to replace the test for transportation with the harmonic vibration tests.
