Analysis of the failure rate assessment models of the radiofrequency cords
.
In this paper the assessment of the reliability of radiofrequency cords was carried out. The analysis of mathematical models of the failure rate assessment of components of the radiofrequency cords was submitted and the optimal model, combining incoming components, was deduced. It was concluded that during the calculation of the reliability of the radiofrequency cords, their models must take into account the maximum number of influencing factors in order to produce adequate results.
