Abstract

Background. When designing printed circuit boards of onboard radio-electronic equipment (OREE), it is necessary to ensure the vibration reliability of the unit. General recommendations are that the radio elements that are most sensitive to external vibration should be positioned closer to the edges of the carrier plate, where the Flexural vibration amplitudes are smaller. But this way is justified only if the entire contour of the carrier Board is fixed and only the amplitude of the external influence is present at the boundary points of the Board. Fixing of real printed circuit boards and OREE boards is very different from fixing along the contour. Therefore, the amplitude of the contour bends can be significant when a particular mode of oscillation is formed. The analysis showed that the problem of placing radio elements on the OREE Board does not have an unambiguous solution in terms of ensuring the vibration stability of the node on the printed circuit Board. A laboratory stand has been created and is being improved at the Department of design and production of radio equipment of PSU, where you can test nonexisting plates of developed components on printed circuit boards. The peculiarity is that the effects on the plate are set from four mini-vibrators located at the corners of the plate. This allows you to set vibrations in the phase at all four points of attachment and get resonant forms that are adequate to odd harmonics; as well as set vibrations in the opposite phase on opposite sides and get forms that are adequate to even harmonics.
Materials and methods. Methods of wave process theory, planning, and mathematical modeling were used in this work.
Results. Conditions for adaptive control of the exciting oscillation task are developed, which allow forming the maximum amplitude of a standing or traveling wave in the required place of the Board. The control is based on a mathematical model of the "black box" type with a step-by-step control of changes in the initial conditions of oscillation excitation.
Conclusions. It is revealed that by changing the phase of external influence at the attachment points, it is possible to control the resonant vibrations of the plate to some extent. Studies have shown that the natural resonant frequencies change or shift, but the forms (modes) of standing and traveling waves are always the same, only the amplitude extremes shift in the plane of the Board.
