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 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. The principles of designing intellectualized technological equipment for car repair production are developed. Approaches to improve the surface quality of parts of machines to be restored during their machining are proposed. The increase of tractor reliability by control of modal values ​​of horizontal accelerations is substantiated. The reasons of low efficiency of measures for increase of durability of running wheels of bridge cranes and vibration resistance of perspective transmission of wheeled tractors and self-propelled chassis are investigated. The approach to restoration of cutting elements of working bodies of earth-moving machines is substantiated. Conceptual bases of quality assurance of metrological support of tests are developed. Uncertainty of test results of wheeled vehicles on brake stands is substantiated. The energy of uneven movement of the car and the change of power and fuel consumption of the engine of a wheeled machine when disconnecting part of its cylinders are studied. The level of energy and heat load of brake mechanisms is predicted. Approaches to increasing the stability of the position of wheeled vehicles using an intelligent on-board electronic system have been improved.
