Study of vehicle component failures and the use of spare parts

The efficiency of using motor transport largely depends on the operational reliability of its rolling stock. The reliability of motor vehicles depends on their proper design, a justified strategy for maintaining their operability during operation. he implementation of this strategy is largely determined by the use of modern information technologies, which include methods and means of diagnostic forecasting of reliability characteristics (failures) of vehicles. The use of modern technologies in the field ofmaintaining the operability of vehicles allows us to ensure their safety conditions, increase the degree of use of the durability of components, reduce downtime during repairs, reduce the consumption of spare parts and materials, etc. The paper presents astatistical analysis of the study of failures of elements of tractor vehicles of 2 brands. The studied failures of parts, units and assemblies of tractor vehicles made it possible to determine the laws of distribution of random variables of the emergence of a need for spare parts. The considered reasons for the occurrence of failures of elements and the use of spare parts of tractor vehicles made it possible to establish that the majority of reasons for the occurrence of malfunctions with asymmetric distribution laws reflect the imperfection of the design, violations of technological assembly processes, and the unsuitability of the rolling stock for operating conditions.
