Implementation of the functional purpose of a technical system depends on its structural composition and the conditions of external influence. Machine-building products are a complex technical system consisting of structural elements interconnected according to the principle of hierarchy (technical system – structural system – element). The functional state of the elements is determined by maintaining the technical parameters within the specified limits during the given time interval. During operation under external load, the mating parts of the contact pair have different degrees of changing technical parameters. In most cases, the resource of one of the contacting elements of the pair is lower, which leads to its repeated replacement until the resource is fully exhausted by the second element. The consumer is primarily interested in the problem of determining the necessary number of element replacements. The solution of this problem is possible by finding out functional dependencies of changes in technical parameters over time for each mating element in the contact pair, taking into account their actual operating time up to the pre-failure state. The use of this methodological approach makes it possible to predict at the design stage the realized level of reliability of the elements, of the contact pair and of the technical system as a whole during further operation of machine-building products.
