Abstract

Background. The existing active shock absorbers are designed to reduce vibra-tion amplitude of radio electronic devices (RED) not only at the resonant frequen-cies, but also over the entire desired frequency range. This approach entails compli-cation of the structure of active shock absorbers by introducing additional means of vibration measuring. The article considers a new option to create a structurally sim-ple means of active vibration protection of RED implementing a method of vibration loads reduction at the resonant frequencies
Materials and methods. The authors selected the most relevant method according to which the structure of the algorithm of feedback signals formation for an informa-tion measuring system (IMS) of the active vibration protection of RED has been de-veloped. The researchers proposed to implement the algorithm on the basis of the ATmega128 microcontroller; for this purpose a theoretical analysis of its processing power was conducted.
Results. The authors have developed the algorithm of feedback signals formation for IMS control in the active vibration protection of RED. The researcher carried out the experimental study of the proposed algorithm’s perfomance in conjunction with the ATmega128 microcontroller. The present algorithm can be implemented in IMS protecting against external vibration effects at frequencies up to 10 kHz.
