Synergetic Model of Electro-Friction Interaction

Abstract

<jats:p>The paper describes algorithms and structure of the electro-friction interaction synergetic model. The results of theoretical modelling and experimental study of sliding electrical contact are given. The comparison of theoretical and experimental results made in the paper proves high validity of the model and its programmatic implementation.</jats:p>

“…It is impossible to explain in the indicated way the most common point sparking and increased sparking under the entire running edge of the SC without the release of sparks. In addition, thermal calculations show [3] that the temperatures of contact clusters in the transition layer of SC very rarely reach the melting and evaporation temperatures of SC materials (steel and graphite: 1500-3200 °C, 3900-4200 °C). A spark discharge cannot occur when the voltage drop on the contact is 2.5-3 V. To ensure the breakdown of the air gap and dielectric surface membranes, kilovolts of voltage are required, which occur in the modes of parametric resonances.…”
