Review and Analysis of Methods for constructing Mathematical Models of Electrical Contacts for Predicting of Contact Radio Interference on Mobile Objects

This article presents an overview and analysis of methods for constructing mathematical models of electrical contacts for predicting contact radio interference on mobile objects. A study of the relationship between the change in the components of the total contact resistance and the predicted contact radio interference is presented. The analysis of three main models of contact resistance is carried out and recommendations on the methodology of applying these methods in the problem of predicting contact radio interference are developed. The obtained results of the analysis of methods for constructing mathematical models of electrical contacts are of great practical and scientific interest, since contact models are the most important basis for predicting contact radio interference. Work in this field allows to increase reliability and provide the required electromagnetic compatibility and noise immunity of devices that are part of connected radio engineering systems.
