Factors affecting on the intensity of changes in the technical condition of vehicles

Abstract

EN: Under different operating conditions, vehicle reliability indicators will vary. The following factors are identified that influence the intensity of changes in the technical condition of cars: production, operating conditions, operational and production. Production factors influencing changes in the technical condition of a car include the design features of a given car brand; homogeneity of production (characterized by dispersion of wear periods for the same parts); reliability. Operating conditions include road conditions, traffic conditions and intensity, natural and climatic, seasonal conditions, environmental aggressiveness. Road conditions and terrain determine the operating mode of the vehicle. They are characterized by the technical category of the road, the type and quality of the road surface, which determine the resistance to vehicle movement, and the elements of the road in plan and profile (road width, curvature radii, slope of ascents and descents). In turn, the operating mode of the vehicle affects the reliability and other properties of the vehicle and its components. Wear and disruption of the road surface increase the risk of failure of vehicle components by 14...33%.
