Object of research processes of disability of elements of motor transport systems, as well as ensuring the reliability and safety of use of machines in the process of their production, operation and repair.
The subject of the research is to establish the relationships between different operational, production and repair factors and operational properties of the elements of motor transport systems.
The purpose of the work is to increase the resource and reliability of motor transport systems by studying the relationship of the relevant performance indicators with the decisions made in the process of production, operation and repair of wheeled vehicles.
Research methods - computer technology engineering, field testing methods, electrical measurement of non-electrical quantities.
A method for assessing the reliability of the driver of an articulated wheeled machine using the criterion of dynamic stability as a diagnostic parameter, taking into account the zones of permissible and unacceptable conditions. It is determined that running in with rollers is the most economical way of finishing, its cost practically does not depend on the initial surface roughness. The structure of functional structures for information-oriented car repair production which can be used at formation of systems of information support of production processes is developed. It is established that the energy losses during the cycle of the cardan transmission depend on the angular velocity of the drive shaft, the amount of torque applied to the cardan transmission, as well as the angle between the axes of the shafts. Analytical expressions are obtained, which can serve as a basis for assessing the energy efficiency of cars when driving in both steady and unstable modes. It is proposed to use the change in the value of partial accelerations during operation as indicators of parametric stability of the dynamic properties of the car. The concept of ensuring the operational properties of wheeled machi
