Development and analysis of models for the formation of contact radio interference under deterministic and random mechanical effects on the contact mechanical joints of moving objects
The article deals with the aspects of applying the general theory of systems to the problems of ensuring electromagnetic compatibility in mobile radio communication complexes. To solve this problem, models were constructed for the formation of contact radio interference under deterministic and random mechanical effects on the contact mechanical connections of moving objects. The dependences of the amplitude of the modulus change and the phase amplitude of the total electric contact current transfer coefficient on the amplitude of this variable contact force were obtained. Contact interference refers to a class of interference created as a result of the influence of the electromagnetic field of a radio transmitter in the near zone on conducting mechanical contacts with a nonlinear and time-varying electrical resistance or on variable contacts that are repeat emitters (secondary emitters) of the electromagnetic field. When moving mobile communication nodes, the frequency division between transmitting and receiving radio devices is determined by the bandwidth affected by contact interference.
