An Algorithm for the Implementation of an Adaptive Vibration Testing System of Onboard Radio-Electronic Equipment

摘要

In designing and creating new original devices of onboard radio-electronic equipment, a very important role is given to the identification of weak points in the structure. Standard vibrating tables with excessive load do not always allow achieving the required vibration acceleration at a given point of the design. It has been revealed that the vibrations are transmitted through the attachment points to the devices not only in phase, but also in anti-phase. In this case, oscillating resonances occur at frequencies that are completely different from those arising during tests on standard vibration equipment. In the proposed system, the position of the oscillation maxima and the acceleration amplitude of the overloads are adaptively controlled. A block diagram for the vibration testing installation and an algorithm for adaptive testing control are presented.
