| Abstract |
Background. In the design and creation of new original devices onboard electronic equipment is very important to identify weaknesses design. Excessive load standard vibration stands do not always allow to achieve the required acceleration at a given point of the structure. The aim of the work is to develop an algorithm for adaptive system of vibration tests of onboard electronic equipment.
Materials and methods. Based on the results of preliminary studies, it is determined that vibrations are transmitted to the device through the attachment points. Moreover, not only in phase, but also in antiphase. At the same time, resonances of oscillations occur in the device at frequencies completely different from the frequencies that arise during tests on standard vibration units. The position of the maxima of the oscillations and the amplitude of the accelerations of adaptive congestion controlled.
Results. The block diagram of the vibration test installation and the algorithm of adaptive control of the test process are presented.
Summary. The results of the work allow us to study all the required points of the Board at the maximum vibration impact at this point and sparing for others; to conduct research on all possible resonant frequencies in a given range; the use of a specialized adaptive system, its techniques and the described algorithm allows us to identify the features of the structures of radioelectronic means with hinged elements in critical modes from the action of external loads and to determine the dynamic characteristics of these structures; the use of these data makes it possible at the design stage to purposefully develop radio-electronic constructs vibration-resistant and vibration-resistant during operation of the product in non-stationary operating conditions.
