Abstract
The article presents the solution of a new scientific and technical problem of substantiating the frequency of diagnosis and the composition of control and diagnostic operations performed during maintenance of machines based on Belarus-82.1. The methodology of justification of the specified parameters of technological processes of maintenance service takes into account the probability of failures in control periods and provides for increased reliability of cars. It is proved that manufacturers in some cases unreasonably increase the frequency of maintenance for advertising purposes. Experimentally determined parameters of the distribution laws of time between failures of component parts of machinery on the basis of the Belarus-82.1. The new dependence of the probability of the failure of the operating time of machines on existing and recommended strategies ensures their efficiency at all the intervals of achievements. The composition of control and maintenance operations for different types of maintenance is justified not only for warranty period and for the entire service life of the machine. The practical use of the research results presented in the article can significantly improve the reliability of equipment with a slight increase in the cost of maintenance.
