Analysis of transport energy efficiency of vehicles in urban conditions of functioning

V. Krupnov

The article analyzes the transport energy efficiency of road trains in urban traffic. Based on the results of multivariate modeling of the traffic-adaptive movement of the road train in the test operation of the urban cycle, the laws of the influence of the increase in its speed dv on the important indicators of the operation of the vehicles were obtained: machine-technological efficiency, transport energy efficiency, operational-cycle fuel consumption and the test energy efficiency coefficient. The article is relevant due to the fact that the methods of organizing cargo transportation by road are based on the theoretical scheme of virtual (intangible) transportation of objects by rolling stock, which does not take into account the resource-technical and technological properties of vehicles. The object of research is technical resources and the technological process of automobile transportation. The purpose of the work is to establish the regularities of the influence of technical parameters on the indicators of transport energy efficiency of road trains, taking into account the change in their speed regimes in the conditions of urban traffic-adaptive traffic. The results of the article can be used in transport companies carrying out transportation in Ukraine.
