Method for adjusting the frequency of vehicles` maintenance based on accounting for the accumulated load impact








The article considers one of the ways of individual adjusting the frequency of vehicles` maintenance. This method has been designed for use in so-called adaptive maintenance systems that allow making a decision about performing technical actions individually for each vehicle, taking into account the specifics of its operation, thereby increasing the effectiveness of measures to ensure technical readiness. Basing on the analysis of the shortcomings of existing analogues, the author proposes the method that focuses on continuous monitoring of parameters that characterize the operation of the vehicle. The method is based on the application of the «energy criterion» and provides for an assessment of the vehicle loading degree and the accumulated load impact. Calculation formulas are given for these values. The adequacy of the method is illustrated with the results of experimental tests. For the practical implementation of the developed method, an algorithm is given that allows taking into account the accumulated load impact to adjust the frequency of the vehicle` maintenance.
